If you move the magnet on the right away from the other magnet what happens to the potential energy?

• the PE decreases because you are moving the magnet against the magnetic field

• the PE increases because you are moving the magnet against the magnetic field

• no need to move

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

• 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.

Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

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

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

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

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

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?

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

• The potential energy increases because Magnet 1 moves 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.
