What are some uses of magnets?
The discovery of magnets was very important as they are used to make electric motors and generators. Things that would disappear if we had no electricity are telephones, lights, electric heat, computers, televisions.
Some uses of electromagnets: Maglev trains, car crushers, scrap metal sorters, telephones, computers, doorbells, tape recorders etc. Maglev trains operate without wheels as they 'float' above the track due to magnetic repulsion between electromagnets in the track and underside of the train. Maglev trains can travel very fast, up to 480 km/h (300 mph).
