Question

do trains use electromagnets? if yes then how?

Answer 1

Answer:

Yes

Explanation:

In maglevs that levitate by magnetic attraction, the bottom of the train wraps around the guideway. Levitation magnets on the underside of the guideway are positioned to attract the opposite poles of magnets on the wraparound section of the maglev. ... These pull the train from the front and push it from behind.
