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)
The energy stored in the field increases because the magnet moves in the direction of the field.
The energy stored in the field decreases because there is no friction.

The correct answer is:
**The energy stored in the field decreases because the magnet moves in the direction of the field.**
When the north pole of one magnet is brought close to the north pole of another magnet, they repel each other. This repulsion causes the potential energy in the system to decrease as the magnets move apart, which is consistent with the notion that work is done against the magnetic field. Thus, the energy stored in the magnetic field decreases.
