Question

Maglev train is a type of train that moves while floating in air just above its track. This way friction is minimized and the train moves very fast−at speeds exceeding 500 km per hour. How do you think it is made to float above the rails?

Answer 1

Maglev trains float above the rails because in these trains, the conventional wheels of the train and the tracks on which they move are replaced by magnets. It is the repulsion property of these magnets which make the Maglev trains float over the tracks. As the train begins to move, the two magnets repel each other as like poles repel. When the magnets repel each other, train is held above its track and as the friction is minimised, the train can reach very high speeds.
