Question

How maglev train run on the tracks?

Answer 1

They don't!

Maglev is a contraction for magnetic levitation.   Something that is levitating is floating above the surface.   The trains are not technically on the tracks,  but  just following them from above.

Answer 2

A basic rule of magnetism is that opposite poles attract each other, and like poles repel each other.  Thus if both the track and the train are magnetically positive (north) they will repel each other, and the train will "float" above the track with little or no friction.

The track also incorporates the functions of a "linear motor."  This incorporates the functions of an electric motor as if it had been "unrolled" into a straight line and pulls the train along continuously by switching the polarities of the magnets at high speed.

There is lots of technical information about maglev devices on the internet.  Do an internet search on "maglev" to find much more information.

Answer 3

Maglev isn't actually "on" the tracks. It floats above them. It's frictionless.

Answer 4

Have you ever tried to hold two magnets together and had them push apart?

Same exact thing runs a maglev train.

Very sophisticated series of electric magnets in the train and in the rail are switched on and off in sequence to lift the train and then push it forward.

Answer 5

The magnets underneath the train repel it from the magnets on the rails, as well as propelling it forward, I believe.
