Question

The north pole of a bar magnet is moved close to the north pole of another bar magnet that is suspended by a thread. How does the energy stored in the magnetic field change?(1 point)
Responses

The energy stored in the field increases because there is no friction.
The energy stored in the field increases because there is no friction.

The energy stored in the field decreases because the magnet moves in the direction of the field.
The energy stored in the field decreases because the magnet moves in the direction of the field.

The energy stored in the field decreases because there is no friction.
The energy stored in the field decreases because there is no friction.

The energy stored in the field increases because the magnet moves in the direction of the field.

Answer 1

When the north pole of a bar magnet is moved close to the north pole of another suspended bar magnet, they experience repulsion due to like poles. As a result, work is done against this repulsion to move the first magnet closer to the second.

In this situation, we can analyze the energy changes involved:

- The energy stored in the magnetic field increases because work is done against the repulsive force of the magnetic fields.

So the correct response would be:

**The energy stored in the field increases because there is no friction.**
