When two magnets with like poles facing each other are brought close together, they experience a repulsive force that tends to push them apart. When they are released, the kinetic energy of their movement increases as they move away from each other.
Initially, when the magnets are close, the magnetic potential energy is higher due to the repulsion between the like poles. As they move apart, the magnetic potential energy decreases and is converted into kinetic energy. Consequently, the energy stored in the system decreases as they move apart.
Therefore, the correct answer is:
**The energy stored decreases.**
