Question

Magnetic Levitation (maglev) trains use electricity to generate magnetic fields. How are these magnetic fields related to the forward motion of the train?

Answer 1

A few countries are using powerful electromagnets to develop high-speed trains, called maglev trains. Maglev is short for magnetic levitation, which means that these trains will float over a guideway using the basic principles of magnets to replace the old steel wheel and track trains.

Answer 2

In maglevs that levitate by magneticattraction, the bottom of the train wraps around the guideway. Levitation magnets on the underside of the guideway are positioned to attract the opposite poles of magnets on the wraparound section of the maglev. This raises the train off the track.
