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. As the magnets move apart due to this repulsion, energy is transferred from potential energy into kinetic energy of the moving magnet.
However, the energy stored in the magnetic field will effectively decrease because as the magnets repel each other, the system works against the magnetic field. Therefore, the response that correctly describes this situation is:
**The energy stored in the field decreases because the magnet moves in the direction of the field.**
This indicates that as the north pole approaches the repelling north pole of another magnet, energy is lost from the magnetic field due to the work done against the magnetic repulsion.
