Answer 1

Correct answer: Magnets in the track and magnets in the bottom of the train repel each other.

Brief explanation: Opposing magnetic fields produce an upward (repulsive) force that lifts the train off the track; electromagnets (or superconducting magnets) and control systems adjust currents to maintain a stable levitation gap.
