When the north pole of a bar magnet is moved close to the north pole of another bar magnet, the two like poles repel each other. The energy associated with their magnetic fields can be understood in terms of work done against this repulsive force.
As one magnet is moved closer to another like-pole magnet, work is done against the repelling magnetic force, which increases the potential energy in the magnetic field configuration. Therefore, the most appropriate response to how the energy stored in the magnetic field changes in this situation is:
**The energy stored in the field increases because the magnet moves in the direction of the field.**
This is because as the magnets approach each other, energy is stored in the magnetic field due to the work done against the repulsive force, even though this might seem counterintuitive since they are moving "in the direction of the field." The key point is that the work done against the repulsive force increases the potential energy in the system.
