Magnetic Fields: Ch. 2 & 3 Review

Front

Cherise sets identical magnetic cats 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? Options: Moving the cart on Track 1 one space to the right (-->), Moving the cart on Track 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.

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

Back

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

Front

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?

Back

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

Front

Based on the two magnetic objects, what type of magnetic forces are we observing?

Back

Attracting

Front

Based on the magnetic field line diagrams, what will happen next with these two set of magnets?

Back

The magnets in Set 1 will repel, and the magnets in Set 2 will attract.

Bryce 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?

Back

The potential energy increases because the train moves against (away) the magnetic force.

LOOK AT THE IMAGE: Lin sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Lin 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?
