Katrina moves a magnetic toy train toward a magnet that cannot move. What happens to the potential energy in the system of magnets during the move?
The potential energy increases because the train moves against the magnetic force
Pablo sets identical magnetic carts on two tracks. At the end of each track is a large magnet that cannot move. Pablo can move the carts one space to the left or one space to the right. Which movement will increase the potential energy in the system the most?
