After the next few articles this is going to start to make you wonder - Are we following some magnetic path too??

Bijal P. Trivedi

October 12, 2001
Do you ever wonder why migrating animals such as birds, salmon, and whales, to name a few, never seem to meander off course and get lost? The answer, according to a couple of new studies, may be that those migration routes and navigation skills are hard-wired into the animals' brains.

Studies of loggerhead turtles revealed that hatchlings have the ability to sense the direction and strength of Earth's magnetic field, which they use for navigating along the turtles' regular migration route.

The migration begins and ends on the shores of eastern Florida. It takes the turtles on a circuit around the Sargasso Sea, an elliptical region in the North Atlantic Ocean that's strewn with seaweed known as sargasso. The entire journey takes five to ten years to complete.

More......"These tiny, defenseless sea turtles embark on this 8,000-mile (12,900-kilometer) migration route around the Atlantic, and they do it alone without following other turtles," said biologist Kenneth Lohmann of the University of North Carolina in Chapel Hill, North Carolina, who led the study.
Long Journey
The loggerhead turtles are less than two inches (five centimeters) long when they emerge from underground nests on the eastern Florida coasts. They crawl straight from their shells and plunge into the Gulf Stream, then into the North Atlantic gyre, a circular current that wraps clockwise around the Sargasso Sea.
The North Atlantic gyre takes the turtles from their Florida nests and east across the Atlantic, past the Azores, south past the Canary and Cape Verde Islands, and finally back toward their birthplace on North American shores.
To determine whether the turtles inherited a migratory map, Lohmann and his colleagues collected baby loggerheads straight from their nests and studied their behavior while exposing them to different magnetic fields.
Each of the 79 loggerheads in the study was outfitted with a blue nylon-Lycra "bathing suit" that was tethered to a tracking system. The turtles were then placed in a shallow circular water tank. Surrounding the tank was a huge electric coil that generated magnetic fields.
Lohmann's team exposed the turtles to magnetic fields that simulated three key locations along the migratory route—northern Florida, the northeastern gyre near Portugal, and the southern gyre—and recorded the direction in which each animal swam.
"We found that turtles followed their migratory route," said Lohmann.
When the turtles were exposed to a magnetic field that mimics the one that occurs near Portugal, for example, the turtles paddled south. In the ocean, the movement in that direction would keep the turtles in warm, nutrient-rich circuit and away from cold waters.

As a young researcher, Peter Klimley decided that it was not only safe but also important to dive freely among hammerhead sharks to acquire a better understanding of the magnificent animals. "I believe you can learn about 80 percent of what's going on in the natural world by observation," he said in a recent interview.

Some people feared disastrous consequences of such a venture. Instead, it put Klimley on the path to becoming a leading shark expert.

 

Klimley, of the Department of Wildlife, Fish, and Conservation Biology at the University of California–Davis, has been studying hammerheads and their behavior for more than 20 years. His observations of their elaborate social rituals and communication have considerably expanded knowledge of one of the most distinctive sharks.

 

There are nine species of hammerheads, which range from three to 20 feet (one to six meters) in length. They are found in the tropical and subtropical waters of oceans around the world. Klimley's current research project focuses on hammerhead sharks' little-known migration habits—knowledge that's important for the conservation of the sharks, and perhaps other marine species.

 

He is looking closely at the curious tendency of hammerheads, as well as other organisms, to school in large groups around underwater mountains. "Since the mid-80s," said Klimley, "I've been arguing that there is a whole assemblage of species that move north and south via stepping stones," or seamounts.

 

Underwater Schooling

 

For more than 20 years Klimley has been studying the behavior of scalloped hammerheads at underwater mountains, or seamounts, such as El Baho Espiritu Santo in the Gulf of California. There, he has observed breathtaking numbers of the sharks.

 

Why they create such a striking spectacle is not completely understood.

 

One thing that seems clear is that the sharks are not gathering at such locations because seamounts are a source of abundant food. In fact, the hammerheads gather at the seamount during the day but feed elsewhere at night. They leave the area at night—alone or in small groups—and spread out through the ocean for miles to feed on fish and squid.

 

Using ultrasonic telemetry, Klimley has tracked this feeding behavior. His research showed that at a certain time in the early morning, the sharks return to the seamount, generally following the same paths with remarkable regularity. They seem to use the underwater mountain as a kind of base.

 

Klimley thinks that the gathering of hammerheads around a seamount and the sharks' movements in the waters beyond may be related to their response to magnetic fields, made possible by the presence of electro-receptors at the bottom of their uniquely shaped heads.

OK - Next time your about to dip that beautiful lobster in the butter sauce you can tell your dining buddies all about magnets and lobsters - who knew??

Brian Handwerk
for National Geographic News

 

January 6, 2003

 

The animal world has its share of celebrated navigators, from flocking geese to spawning salmon. A rather unlikely character, however, may soon take its place among the best of them.

 

New research suggests that Caribbean spiny lobsters, despite their limited intelligence, may be among the animal kingdom's top navigators. Their homing abilities could also provide scientists with new clues to the long-debated role of the Earth's magnetic fields in animal movements and migrations.

 

Larry C. Boles and Kenneth J. Lohmann, researchers at the University of North Carolina in Chapel Hill, reported their findings in the January 2003 issue of Nature. Their research suggests that spiny lobsters are able to determine their location on Earth even when transported to an unfamiliar area. The lobsters are the first invertebrates to display this ability known as true navigation.

 

Animals capable of true navigation can determine their position without relying on recognizable surroundings, cues that originate from a destination, or information collected on the journey to a given location. Only a few animals have been shown to possess true navigation—and all but the lobster are vertebrates. Birds such as the homing pigeon comprise most of the short list. However, there is some evidence that sea turtles and at least one type of migratory salamander also use true navigation.

 

In previous research, Boles and Lohmann found that Caribbean spiny lobsters used an internal magnetic compass that enables them to determine the four cardinal directions: north, south, east, and west. "That's not very unusual in the animal world," Boles said, "but it's one important tool you need to be good navigator."

 

"We know that lots of animals use the earth's magnetic field as a compass," said Charles Walcott, a professor of neurobiology and behavior at Cornell University in Ithaca, New York, and a longtime homing pigeon researcher. "But if you become lost, a compass cannot tell you where you are. What's exciting about this new work is that it provides pretty strong evidence that [Caribbean spiny lobsters] use this field not just for direction but to know where they are on the Earth."

 

Boles explained that many considered the lobsters unlikely candidates to possess advanced navigational skills like true navigation.

 

"I think that a big issue is the general thought that invertebrates, because of their relatively simple nervous systems, might not have the necessary mental capacity to do this kind of thing," Boles told National Geographic News. "They are doing the most sophisticated kind of navigation with a much simpler nervous system than other animals."

 

Test Designed to Disorient Lobsters

 

The Caribbean spiny lobster (Panulirus argus) is commonly found in the western Atlantic Ocean in an area stretching from Brazil to Bermuda. Some populations are migratory, but most spend their daylight hours inside coral reef dens, emerging at night to forage before returning to their homes.

 

To test the lobsters' navigation abilities, researchers Boles and Lohmann developed complicated measures to disorient and confuse the animals. The researchers were careful to ensure that lobsters were not able to determine their location from sensory information gathered while being moved.

Well you have heard alot about "Global Warming" but have you heard about the Earth's magnetic field fading? Read on....

 

John Roach

September 9, 2004

 

Earth's magnetic field is fading. Today it is about 10 percent weaker than it was when German mathematician Carl Friedrich Gauss started keeping tabs on it in 1845, scientists say.

 

If the trend continues, the field may collapse altogether and then reverse. Compasses would point south instead of north.

 

Not surprisingly, Hollywood has already seized on this new twist in the natural-disaster genre. Last year Tinseltown released The Core, a film in which the collapse of Earth's magnetic field leads to massive electrical storms, blasts of solar radiation, and birds incapable of navigation.

 

Entertainment value aside, the portrayal wasn't accurate, according to scientists who say the phenomenon of Earth's fading magnetic field is no cause to worry.

 

"The field has reversed many times in the past, and life didn't stop," said Gary Glatzmaier, an earth scientist and magnetic field expert at the University of California, Santa Cruz.

 

Glatzmaier is keeping an eye on our planet's weakening magnetic field as he tries to learn more about how Earth's geodynamo works. The geodynamo is the mechanism that creates our planet's magnetic field, maintains it, and causes it to reverse.

 

Magnetic Shield

 

Earth's geodynamo creates a magnetic field that shields most of the habited parts of our planet from charged particles that come mostly from the sun. The field deflects the speeding particles toward Earth's Poles.

 

Without our planet's magnetic field, Earth would be subjected to more cosmic radiation. The increase could knock out power grids, scramble the communications systems on spacecraft, temporarily widen atmospheric ozone holes, and generate more aurora activity.

 

A number of Earth's creatures, including some birds, turtles, and bees, rely on Earth's magnetic field to navigate. The field is in constant flux, scientists say. But even without it, life on Earth will continue, researchers say.

 

"There are small fluctuations, which lead to nothing, and large ones, which we know from the geologic record are associated with reversals," said Peter Olson, a geophysicist at Johns Hopkins University in Baltimore, Maryland.

MRAM breakthrough adds ability to maintain data when powered down

 

 

Updated: 6:22 a.m. PT July 10, 2006

 

DALLAS - Achieving a long-sought goal of the $48 billion memory chip industry, Freescale Semiconductor Inc. announced the commercial availability of a chip that combines traditional memory's endurance with a hard drive's ability to keep data while powered down.

 

The chips, called magnetoresistive random-access memory or MRAM, maintain information by relying on magnetic properties rather than an electrical charge. Unlike flash memory, which also can keep data without power, MRAM is fast to read and write bits, and doesn't degrade over time.

 

Freescale, which was spun off of Motorola Inc. in July 2004, said Monday it has been producing the 4-megabit MRAM chips at an Arizona factory for two months to build inventory.  A number of chip makers have been pursuing the technology for a decade or more, including IBM Corp.

Recently, a number of articles have been published on static magnetic therapy. Static magnetic therapy is the placement of a magnet field on or near the body to enhance healing, relieve pain and improve body function. The idea of magnetism is not new. Early Chinese medical literature claimed healing properties for lodestrone, a naturally magnetic mineral. For centuries, static magnetic therapy has been used by eastern practitioners to relieve pain and swelling, and to induce healing. Since the 1950's, numerous Japanese studies have been conducted on the effectiveness of magnetic fields for treating various conditions. Many magnetic devices are registered with the Japanese Welfare Ministry as medical devices, after undergoing clinical testing at accredited medical institutions to verify their safety and effectiveness.

For many years, the Magnetic Health Science Foundation has been meeting annually in Japan to report on the growing body of evidence of the scientific technology of magnetic research. To date, there are now over 300 published articles on magnetic research.

But, do magnets really work? The answer may lie in understanding the laws of physics, and in reviewing recent scientific evidence.

We are energetic beings surrounded by naturally generated electromagnetic energy, fields of energy which are created by the spinning and moving of electrons and charged particles within the cell.

Some of the early awareness of the importance of electromagnetic energy fields was discovered when the Russian cosmonauts first spent long periods of time on board the Mir space station; they became sick. Their illnesses appeared to be caused by the lack of contact with the magnetic field surrounding the earth. Once the Russian space station was equipped with a magnetism generator, the symptoms disappeared.

All cells within the body are ordered by magnetism; the atoms and molecules are tiny magnets with a positive and negative pole. All communication within the body occurs through electric currents and the electromagnetic frequencies they generate.

According to the laws of physics, the first law of electromagnetism states that if an electron or other charged particle is moving it generates a magnetic field. The corollary to this rule is that if an electron or charged particle encounters a magnetic field it must move.

So how does this apply to magnetic therapy, healing, and pain? When a person is injured, the body immediately reacts to restore the body to its natural balanced state. In brief, the injured tissue produces a chemical reaction whereby acids are released and chemicals are brought to the injured site to begin a healing process. This chemical reaction leads to swelling which causes pain.

The theory is that when a magnetic field is placed at or near the injured site the electromagnetic field induces a current or charge in the tissues in the body. This charge causes the toxins (acids and other chemicals) to move, the toxins are removed and excreted, and a natural healing state ensues. As this change occurs, the blood flow to the injured site is improved, the swelling is reduced, and pain is alleviated.

Some scientists believe that magnetic therapy causes the body to dispose of waste materials (toxins) more quickly and speeds up the healing process. Numerous studies have been conducted on the effects of static magnetic therapy in Asia and Europe. Recently, scientists in the US have begun reporting their results of the effectiveness of magnetic fields.

Magnetic therapy has been found to be effective in alleviating burning, numbness and tingling, and exercise induced foot pain in patients with diabetic neuropathy (Weintraub 1998, 1999, 2003); in alleviating neuropathic pain in patients with carpal tunnel syndrome (Weintraub & Cole 2000); in alleviating pain in people suffering from osteoarthritis in the knees and hips (Harlow 2004, Hinman 2002, Pipitone 2001, Wosko 2004); and in other chronic conditions such as rheumatoid arthritis (Segal 2001), fibromyalgia (Alfono 2001, Thomas 2001) and chronic back pain (Collacott 2000).

Although the scientific research in the United States is still in the early stages compared to the Asian and European studies, static magnetic therapy has been shown to have no detrimental side effects and has great promise for those suffering from chronic painful conditions.

Introduction

Many of us believe our daily experience with magnets begins and ends on the refrigerator door. There’s that cute shot of the kids in the magnetized frame, the clip holding the grocery list, the realtor’s business card and the haiku composed of magnetized words.

In fact, those are just one of several types of magnets that span a broad range of sizes, shapes, materials, strengths and applications. You may not see them, but magnets are everywhere – in our car motors, phones, tape recorders, credit cards, stereo speakers and computers, to name just a few practical applications. That’s not even to mention the enormous – and enormously powerful – magnets used at the Magnet Lab and other research institutions.

PHYSICS FACTOID: Scientists believe the Earth's magnetic field is a result of convection currents in the planet's liquid outer core, which makes a good conductor because it is made up largely of iron. This is called a geodynamo.

Some magnets last lifetimes, others come and go in the blink of an eye. Some are multi-ton behemoths, others only visible through a microscope. Some are molded by nature, others by man. Magnets also span a vast range of possible magnetic field strengths.

On the following pages we’ll review the basic types of magnets. But remember that there are properties that all magnets have in common. They all exert a magnetic force on each other. They all have a south pole and a north pole (just like the Earth, which itself is a magnet); opposite poles attract, like poles repel. In all magnets, the magnetic field lines run from south to north, and these fields are what produce forces on other magnets that follow specific physical laws.

The fields of electricity and magnetism are intimately intertwined. However, humankind’s knowledge of magnetism and static electricity began more than 2,000 years before they were first recognized to be separate (though interrelated) phenomena. Once that intellectual threshold was crossed – in 1551 – scientists took more bold steps forward (and more than a few steps back) toward better understanding and harnessing these forces. The next 400 years would see a succession of discoveries that advanced our knowledge of magnetism, electricity and the interplay between them, leading to ever more powerful insights and revolutionary inventions.

This timeline highlights important events and developments in these fields from prehistory to the beginning of the 21st century. It also includes related developments in other disciplines (such as the evolution of computers). 

600 BC - 1599 - Humans discover the magnetic lodestone as well as the attracting properties of amber. Advanced societies, in particular the Chinese and the Europeans, exploit the properties of magnets in compasses, a tool that makes possible exploration of the seas, “new worlds” and the nature of Earth’s magnetic poles.

1600 - 1699 - The Scientific Revolution takes hold, facilitating the groundbreaking work of luminaries such as William Gilbert, who took the first truly scientific approach to the study of magnetism and electricity and wrote extensively of his findings.

1700 - 1749 - Aided by tools such as static electricity machines and leyden jars, scientists continue their experiments into the fundamentals of magnetism and electricity.

1750 - 1774 - With his famous kite experiment and other forays into science, Benjamin Franklin advances knowledge of electricity, inspiring his English friend Joseph Priestley to do the same.

1775 - 1799 - Scientists take important steps toward a fuller understanding of electricity, as well as some fruitful missteps, including an elaborate but incorrect theory on animal magnetism that sets the stage for a groundbreaking invention.

1800 - 1819 - Alessandro Volta invents the first primitive battery, discovering that electricity can be generated through chemical processes; scientists quickly seize on the new tool to invent electric lighting. Meanwhile, a profound insight into the relationship between electricity and magnetism goes largely unnoticed.

1820 - 1829 - Hans Christian Ørsted’s accidental discovery that an electrical current moves a compass needle rocks the scientific world; a spate of experiments follows, immediately leading to the first electromagnet and electric motor.

1830 - 1839 - The first telegraphs are constructed and Michael Faraday produces much of his brilliant and enduring research into electricity and magnetism, inventing the first primitive transformer and generator.

1840 - 1849 - The legendary Faraday forges on with his prolific research and the telegraph reaches a milestone when a message is sent between Washington, DC, and Baltimore, MD.

1850 - 1869 - The Industrial Revolution is in full force, Gramme invents his dynamo and James Clerk Maxwell formulates his series of equations on electrodynamics.

1870 - 1879 - The telephone and first practical incandescent light bulb are invented while the word “electron” enters the scientific lexicon.

1880 - 1889 - Nikola Tesla and Thomas Edison duke it out over the best way to transmit electricity and Heinrich Hertz is the first person (unbeknownst to him) to broadcast and receive radio waves.

1890 - 1899 - Scientists discover and probe x-rays and radioactivity, while inventors compete to build the first radio.

1900 - 1909 - Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

1910 - 1929 - Scientists’ understanding of the structure of the atom and of its component particles grows, the phone and radio become common, and the modern television is born.

1930 - 1939 - New tools such as special microscopes and the cyclotron take research to higher levels, while average citizens enjoy novel amenities such as the FM radio.

1940 - 1959 - Defense-related research leads to the computer, the world enters the atomic age and TV conquers America.

1960 - 1979 - Computers evolve into PCs, researchers discover one new subatomic particle after another and the space age gives our psyches and science a new context.

1980 - 2003 - Scientists explore new energy sources, the World Wide Web spins a vast network and nanotechnology is born.

We have all ridden the monorail at Disneyland or the high speed magnetic levitation trains in Japan, right? Well truth be told many of us have not and even for those of us that have experienced these exhilarating modes of transportation not much knowledge as to the “How” and “why” of it all is really understood. Read on and increase your “magnetic” knowledge base….

A high-speed rail technology by which a train can travel free of friction at speeds of 480 kilometers (300 miles) per hour or more. The train is suspended on a magnetic cushion about half an inch above an elevated magnetic track, whose moving magnetic field alternately attracts and repels magnets mounted on the train, which is pushed and pulled along by this process.

A method of supporting and transporting objects or vehicles which is based on the physical property that the force between two magnetized bodies is inversely proportional to their distance. By using this magnetic force to counterbalance the gravitational pull, a stable and contactless suspension between a magnet (magnetic body) and a fixed guideway (magnetized body) may be obtained. In magnetic levitation (maglev), also known as magnetic suspension, this basic principle is used to suspend (or levitate) vehicles weighing 40 tons or more by generating a controlled magnetic force. By removing friction, these vehicles can travel at speeds higher than wheeled trains, with

Questions that often come up are, "How do magnets work?", or, "Why is iron magnetic?", or, "What makes a magnet?", or, "What is the magnetic field made of?".

Those are good questions, and deserve a good answer.  However, did you know that there is a lot about magnets at the atomic level that isn't known yet?  Just like with most of the other basic forces we are familiar with, such as gravity, electricity, mechanics and heat, scientists start by trying to understand how they work, what they do, are there any formulas that can be made to describe (and thus predict) their behavior so we can begin to control them, and so on. 

The work always starts by simple observation (that's the fancy word for playing around with the stuff!).  That's why it's so important to have some "hands-on" experience with magnets.  Have you taken two magnets and tried to push like poles together?  How far away do you start to feel the repulsion?  How does the force vary with the distance between them?  When the magnets are moved off-axis to each other (moving them to the side and not head on) what does it feel like?  Could you describe it like trying to push two tennis balls together?  When you flip one around, what changes?  What about moving one around the other in a circle?  Try these things!  That's how you learn!  Only when you play with (observe) them will you begin to understand how they work. This is the stuff great scientific pioneers did, like Faraday, Lenz, Gilbert, Henry and Fleming.

In our never ending quest for knowledge regarding magnets, living organisms and credible science we found the following article incredibly interesting. Take a read and give us your comments on the usefulness and interest level of this and any other of our postings we hope you find conveniently put together on one source blog.acemagnetics.com

 

Of Mice & Magnets

BY FRANK STEPHENSON

 

 


We do not deny the possibility of there being invented some day magnets enormously more powerful than any yet known to us, which may produce effects upon the nervous system perceptible to some of the sensory organs".
For the time, the comment might well have been taken as a magnanimous concession by learned men of science to noisy boosters of using simple magnets to cure the sick.
Surely stung by the final conclusion reached by the writers—their research equated the benefits of using magnets as medicine to those of being treated with a block of wood—at least the advocates of magnetic therapy had gotten their day in scientific court.
The year was 1892. The experiment, conducted at the Edison Laboratory in Orange, New Jersey, was aimed at testing claims made by "adherents and earnest promulgators" of using magnets to treat various human ailments. Dr. Frederick Peterson, chief neurologist at the New York College of Physicians and Surgeons, and A.E. Kennelly, the Edison lab's chief electrician, had reached their findings after exposing frogs, a dog and finally a boy to the strongest magnetic field ever used in such a test—a field 300 times stronger than Earth's own magnetic field.
Peterson and Kennelly were unequivocal. If magnets of such great power had no observable effects on living things, then it surely followed that the ordinary magnets in the hands of dubious medical practitioners of the day had none either. It was a skeptic's holiday.
Turn the clock up a century, and picture Peterson and Kennelly standing in front of a typical, experimental magnet within the National High Magnetic Field Laboratory in Tallahassee, Florida. Imagine their awe at seeing a live frog levitated, afloat on invisible forces strong enough to defy gravity; or seeing magnetically drawn pictures of the insides of a living brain.
Or seeing what happens to a Tom Houpt rat.

Last year, Houpt, a young Ph.D. from Harvard and an FSU biologist only since 1997, shared a genuinely rare moment in science with colleague and veteran researcher Jim C. Smith as the two men followed up on a hunch..... Read on

Gauss? What is it, who is it named after? Where and when did gauss obtain this “identity?” Let’s take a walk back in time and look at the who, where and when of magnets and Gauss…

  Public interest in science owes a great deal to Alexander Von Humboldt (1769--1859). As a young man Alexander explored the jungles of South America, but much of his life was spent in Paris, where he tirelessly drew the public's attention to the achievements of the natural sciences. Late in life he assembled his scientific knowledge into a monumental set of volumes titled " Kosmos."

  Carl Friedrich Gauss

   In a 1828 meeting Humboldt suggested to the greatest German mathematician of his time, Carl Friedrich Gauss, that he ought to apply his talents to the mysteries of magnetism. Gauss and his associate Weber then built a laboratory to study magnetism, in which, among other things, they devised the world's first magnetic telegraph.

   Up to that time, the compass needle--and the downward-pointing "dip needle" on a horizontal axis--measured well the direction of the magnetic force, but what about measuring its strength? Gauss devised a clever method

When it comes right down to it the fact that almost every planet we know of exhibits a degree of magnetism shows the significance of magnets not only here but in fact as part of the "fabric of our universe".


 

It is not as if in our everyday lives we walk around and think about the relationship between magnetism and the planets. In fact almost all planets that we know of in our solar system have or have had a magnetic component similar to earth’s magnetic field. One planet does not have a magnetic component but why? Read on and expand your “internal universe”…..

Until the middle of the 20th century the Earth's magnetism seemed to be a happy accident of nature. Too many factors had to fit just right--the fluid core of the Earth, its electrical conductivity and its motions, all had to satisfy the strict requirements of dynamo theory. That was before other planets in the solar system were visited and examined. Now we know that among those planets, only Venus lacks any magnetism. The planets differ greatly in size and properties, and their fields differ too. Yet they all seem to have dynamo fields, or (in the case of Mars and the Moon) have had them in the past.

    In early 1955, two young radio-astronomers started working with a cross-shaped antenna array of the Carnegie Institution's Department of Terrestrial Magnetism (DTM). The array stood on the north shore of the Potomac River (upstream from Washington, DC and slightly south of White's Ferry; more here) and could select signals from a narrow range of directions. Ken Franklin and Bernie Burke calibrated it using a known source, the Crab Nebula, and then began surveying the surrounding sky.

We find it incredibly ingenious to think of tapping into the power of magnets to address the problem of jetlag. Here is but another example of an “unproven” science being considered by a pretty credible source. This does not mean magnets work but it does provide yet another thread in the long tapestry of possible applications of magnets and the human race. If nothing else this “invisible force” continues to intrigue and capture our attention and curiosity even still…..What do you think? Let us know if you have a “Magnetic” story to tell by responding to this article on our blog – Thank you

 

Airbus patenting way to eliminate jet lag

New! Comment | Email | Print | Rated: 90% by 1 user(s).

Jet lag sucks. There is nothing worse than feeling like you have been run over by a truck after you fly somewhere. Airbus is seeking a patent for a device that they claim will make jet lag a distant memory.

The solution involves some sort of "electromagnetic interaction" that would be in each passenger's seat. Kind of like one of those magnetic bracelets that is supposed to do wonders I guess, only not in bracelet form.

Airbus claims in the patent application that the technology can prevent and reduce jet lag, make people feel more relaxed, promote sleep, reduce stress and even cut down on thrombosis. Sounds great, but the only thing I can think of is that magnets and credit cards aren’t friends, so everyone could end up with useless pieces of plastic after a flight. I’m sure they’ve thought of that, though... right?

There’s no word, of course, if and when this would actually show up in a plane.

Iron filings in a magnetic field generated by a bar magnet

A magnet is an object that has a magnetic field. It can be in the form of a permanent magnet or an electromagnet. Permanent magnets do not rely upon outside influences to generate their field. They occur naturally in some rocks, but can also be manufactured. Electromagnets rely upon electric current to generate a magnetic field - when the current increases, so does the field.

Using Magnets to Deliver Medication

By Vivian Richardson, Ivanhoe Health Correspondent

CHICAGO (Ivanhoe Newswire) -- It's still a long way off, but one day doctors may use magnets placed both inside and outside a patient's body to direct medications to a precise location. A new study reveals the concept works in animals.

Engineers and doctors at Drexel University in Philadelphia wanted to find a way to re-medicate stents -- small wire mesh tubes used to hold blood vessels open. In the past, these "scaffolding" devices for diseased or damaged blood vessels would sometimes cause a new blockage until doctors developed drug-eluting stents. The medications coated on the device helps keep the vessels healthy. When the medication runs out, clots can sometimes form and lead to heart attacks or strokes.

"Stents are limited at this point to the single dose that is on the stent at the time of surgery," Frederick Stoddard, M.D., a surgical resident at Drexel University College of Medicine, told Ivanhoe. He helped create and test a magnetic stent along with Zachary Forbes, Ph.D. When magnetized medications are injected into the patient, the drugs are attracted to the magnetic stent. "One of the great things about this is that we can target the stent with virtually any drug we want repeatedly. We can do this through intravenous injection, which means you don't have to do an additional invasive procedure," Dr. Stoddard said.

"I know of no scientist who takes this claim seriously...It's another fad. They come and go like copper bracelets and crystals and all of these things, and this one will pass too." --Robert Park of the American Physical Society.

"Iron atoms in a magnet are crammed together in a solid state about one atom apart from one another. In your blood only four iron atoms are allocated to each hemoglobin molecule, and they are separated by distances too great to form a magnet. This is easily tested by pricking your finger and placing a drop of your blood next to a magnet. " --Michael Shermer*

Anecdotal benefits have been reported by wearers but studies comparing these bracelets with 'dummy' versions have produced mixed results.

The current British Medical Journal study found a significant reduction in pain scores among 65 wearers.

The Peninsular Medical School team said the effect could be real or down to the individual's faith in the treatment.
