Critical Juncture: Magnetic Fields (Amplify Science)

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

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

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

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.

Pablo sets identical magnetic carts on two tracks. At the end of each track is a blue 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?

Moving the cart on Track 1 one space to the left (←).

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

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

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 decreases because Magnet 1 moves in the same direction as the magnetic force.

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

Moving the Car 1 car one space toward the center magnet.

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

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

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 decreases because the train moves against the magnetic force.

Peter sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Peter 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?

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

Jerome puts two magnetic vehicles very close to each other. What will happen next, and why?

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

In a computer simulation, Ayesha moves a magnet (Magnet 2) away from another magnet (Magnet 1) that cannot move. Which statement accurately describes the change in potential energy?

The potential energy increases because Magnet 2 moves against the magnetic force.

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

Moving Car 2 one space away from the center magnet.
