What happens to the potential energy in the system, when the magnetic train is moved away from the stationary magnet?

• The potential energy increases because the magnet is moved against the magnet force.

• The potential energy decreases because the magnet is moved against the magnet force.

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 increases because Magnet 1 is moved against the magnetic force.

• The potential energy decreases because Magnet 1 moves against the magnetic force.

• The potential energy decreases because Magnet 1 moves in the same direction as the magnetic force.
