How do electromagnets move a maglev train in regards to levitation and then propulsion? (select two) (2 points)

Question

Magnets in the track attract magnets in the train's undercarriage, levitating the train.

Magnets in the track repel magnets in the train's undercarriage, levitating the train.

Magnets in the sides of the tracks constantly repel and attract magnets in the sides of the train, propelling the train forward.

Magnets in the sides of the track constantly switch on and off, propelling the train forward.

Answer 1

The correct options are:

1. Magnets in the track repel magnets in the train's undercarriage, levitating the train.

2. Magnets in the sides of the tracks constantly switch on and off, propelling the train forward.

These two processes are essential in how maglev trains achieve both levitation and propulsion using electromagnetic forces.
