A magnet is moved close to a rubber band. How does the energy stored in the magnetic field change?

Question

Responses

The energy stored in the magnetic field does not change.

The energy stored in the magnetic first increases and then decreases.

The energy stored in the magnetic field increases.

The energy stored in the magnetic field decreases.

Answer 1

The correct response is: The energy stored in the magnetic field does not change.

If the magnet is moved close to a rubber band, it does not directly affect the magnetic energy stored in the field itself. The rubber band is not a magnetic material and does not interact with the magnetic field in a way that changes the energy stored in the magnetic field. Therefore, the energy in the magnetic field remains constant regardless of the magnet's position relative to the non-magnetic rubber band.
