So Many Questions So little time
With so many questions and so little time to absorb the magnitude of data available on magnets fromn so many diffferent sources we endeavor to present a one stop shop so to speak when ever you want to "feed you head" with more magnetic information
Get a Straight Answer
Listed below are questions submitted by e-mail to the author of "The Great Magnet, the Earth." Some of them (marked ***) came in response to an earlier site "The Exploration of the Earth's Magnetosphere" and are also found there in the question-and-answer section. Only some of the questions that arrive are listed, either because they keep coming up again and again--on the reversal of the Earth's magnetic field, for instance--or because the answers add extra details, which might interest other users.
