When two magnets with like poles facing each other (for example, two north poles) are brought close together, they repel each other due to magnetic repulsion. As they are held close, potential energy is stored in the system due to this repulsive force. When the magnets are released, they will move apart, and the potential energy that was stored will convert into kinetic energy as they accelerate away from each other.
Initially, when they are close together, the energy stored is relatively high, and as they move apart, the potential energy decreases while kinetic energy increases. Therefore:
**The energy stored decreases.**
Once the magnets are released and start moving apart, the overall energy may appear to decrease as the magnetic potential energy is converted into kinetic energy of the moving magnets.
