Maglev is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.

What are maglev trains?

maglev, also called magnetic levitation train or maglev train, a floating vehicle for land transportation that is supported by either electromagnetic attraction or repulsion.

How does maglev train work?

In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. ... Here, both magnetic attraction and repulsion are used to move the train car along the guideway.
