In a computer simulation, Ayesha moves a magnet (Magnet 2) away from another magnet (Magnet 1) that cannot move. Which statement accurately describes the change in potential energy?
The potential energy does not change because the magnets in the system do not change.
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.
The potential energy increases because Magnet 2 moves against the magnetic force.
