Question

An experiment modeled the interaction between magnetic force and the change of energy of an object influenced by the magnetic force. The experiment’s researchers observed that the metal wheels of a small car turned as they experienced the force exerted by a magnetic field, drawing the car closer to the magnet. What energy is being gained by the car?(1 point)

Answer 1

kinetic energy

The magnetic force does work on the car, causing it to move and its speed to increase, so the car gains kinetic energy (some small amount may also dissipate as heat).
