Magnetic Field Potential Energy

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.

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?

• Moving the cart on Track 1 one space to the right (→).

• Moving the cart on Track 2 one space to the left (←).

• Moving the cart on Track 2 one space to the right (→).

• All these movements will result in the same change in potential energy because they each move a cart the same distance.

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.

An engineer is investigating potential energy with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. To test her ideas, the engineer will move one car one space. Which movement will result in the largest increase in potential energy?

• Moving Car 1 one space toward the center magnet.

• Moving Car 2 one space away from the center magnet.

• Moving Car 2 one space toward the center magnet.

• All these movements will result in the same change in potential energy because they each move a roller coaster car the same distance.

• 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.
