What happens to the potential energy?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy increases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.
