In a computer simulation, Juan moves a magnet (Magnet 1) closer to another magnet (Magnet 2) that cannot move. Which statement accurately describes the change in potential energy?
a The potential energy does not change because the magnets in the system do not change.
b The potential energy increases because Magnet 1 moves against the magnetic force.
c The potential energy decreases because Magnet 1 moves against the magnetic force.
d The potential energy decreases because Magnet 1 moves in the same direction as the magnetic force.

The correct answer is: b The potential energy increases because Magnet 1 moves against the magnetic force.
Explanation: When Juan moves Magnet 1 closer to Magnet 2, he is moving it against the magnetic force exerted by Magnet 2. This means work is done on Magnet 1 to move it against the repulsive (or attractive) force, which increases the potential energy of the system. In simple terms, moving against a force increases potential energy.
