When the north pole of a bar magnet is moved close to the north pole of another bar magnet, the two like poles will repel each other. This interaction leads to an increase in potential energy in the magnetic field as work is done against the repulsive force to bring the two magnets closer together.
However, since the question is focused on the energy change in the magnetic field itself during this process, the correct response is:
**The energy stored in the field increases because the magnet moves in the direction of the field.**
This is appropriate because the movement of the magnet against the repulsive force requires energy input, resulting in an increase in magnetic potential energy in the configuration.
