Amplify Science Magnetic Fields Chapter 2 Quiz

The letters N and S show the magnetic poles. Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

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

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

• 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.

The letters N and S show the magnetic poles. Dakota moves a magnetic toy train toward a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

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

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

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

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

The letters N and S show the magnetic poles. In a computer simulation, Noni moves a magnet (Magnet 1) away from 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 decreases because Magnet 1 moves in the same direction as the magnetic force.

• The potential energy decreases because Magnet 1 moves against the magnetic force.

• The potential energy increases because Magnet 1 moves against the magnetic force.
