What happens to potential energy in a system of magnets when they are released?

Back

The magnetic force changes potential energy into kinetic energy.

Front

How do magnets store potential energy in a magnetic field?

Back

The energy used to move a magnet against (opposite direction as) a magnetic force.

What device uses a free-moving magnetic needle to show direction?

Back

Compass.

Front

What occurs when magnets are let go?

Back

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