When the north pole of one bar magnet is moved close to the north pole of another bar magnet, they will experience a repulsive force due to their like poles. This creates a situation where work is done against this repulsive force when moving them closer together.
As a result, the energy stored in the magnetic field decreases because the system is moving toward a configuration that is less stable (in terms of magnetic potential energy) when like poles are brought close together.
Therefore, the correct response is:
**The energy stored in the field decreases.**
