When the north pole of a bar magnet is moved close to the north pole of another bar magnet, they experience repulsion due to their like magnetic poles. This means that work is done against the magnetic field when moving one magnet toward the other.
In terms of energy storage in the magnetic field, as the magnets repel each other and work is done against this repulsion, energy is added to the system. Therefore, the energy stored in the magnetic field actually increases when you consider the work done to move the magnet closer despite the repulsion.
So, the correct response would be:
**The energy stored in the field increases because there is no friction.**
