Question

what are maglev vehicles?

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

Those vehicles which are based on magnetic transport are known as maglev vehicles.
As much known by me the track on which the maglev vehicle relocates are magnetic and there are magnets which are attached to the maglev vehicle.
It's most probably like this
The place where it sticks is south pole or north pole but even where the magnets are present are of the same kind .So as it tries to repulse it moves or relocates.Its based on electro magnetism
