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

Answer 1

Select these two:

- Magnets in the track repel magnets in the train's undercarriage, levitating the train.
- Magnets in the sides of the track constantly switch on and off, propelling the train forward.

Explanation: levitation is provided by magnetic repulsion (or in some designs by controlled attraction), and propulsion is done by a linear motor — coils in the guideway are energized in sequence (creating a moving magnetic field) that pulls and then pushes the train forward.
