An engineer is experimenting with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. The engineer is planning to move one car one space. Which movement will result in the largest increase in potential energy?
a Moving Car 1 one space toward the center magnet.
b Moving Car 1 one space away from the center magnet.
c Moving Car 2 one space away from the center magnet.
d All these movements will result in the same change in potential energy because they each move a roller coaster car the same distance.

The correct answer is: a) Moving Car 1 one space toward the center magnet.
Explanation: Potential energy in a magnetic field is related to the distance between the magnet and the objects affected by the field. When Car 1 is moved closer to the center magnet, it experiences an increase in potential energy due to the stronger magnetic forces acting on it as it gets nearer to the magnet. Moving it away or moving Car 2 away will decrease or have a neutral effect on the potential energy in this context, while moving closer increases it.
