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.
What is a maglev train and how it works?
Maglev (from magnetic levitation) 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.
How do magnetic trains run without touching the ground?
Maglev is a transport method that uses magnetic levitation to move vehicles without touching the ground. A maglev train floats above the tracks on a "cushion" of magnetic field.
