Question

1. Friction is reduced in a moving maglev train by lifting it above its track by magnetic repulsion.
What are the advantages of reducing friction between the train and the track?​

Answer 1

Answer:

Maglev is short for Magnetic Levitation. Hence, the train is using magnetism to reduce friction. By having magnets on the track be opposed to magnets on the bottom of the train, the magnetic repulsion keeps the train levitating slightly above the tracks. This means that train is essentially riding on air, which has way less friction than a wheel on a metal track.

Answer 2

it will not make the track less efficient

no wear and tear will be done

unnecessary heat will not be produced
