Eli is holding two magnets close to each other. What will happen when he lets go?

• The magnets will not move because the magnets are not touching.

• The magnets will move closer to each other because the magnetic force will pull the magnets together.

• The magnets will move away from each other because the magnets are not touching.

• The magnets will move away from each other because the magnetic force will push the magnets apart.

Ramon puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

• The trains will move closer to each other because the magnetic force will pull the trains together.

• The trains will not move because the magnets are not touching

• The trains will move away from each other because the magnetic force will push the trains apart.

• The trains will move away from each other because the magnets are not touching.

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?

• 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.
