When two magnets with like poles facing each other are brought close together, they experience a repulsive force. This repulsion means that work must be done to bring them closer, and as they are released, they will move apart.
The energy in the system can be understood in terms of potential energy: as the magnets are pushed closer together (fighting against the repulsive force), potential energy is stored. Once released, they move apart, and that potential energy is converted into kinetic energy, resulting in a decrease in the potential energy of the system.
Thus, the correct response is:
**The energy stored decreases.**
