Magnetic Fields Student Review

Front

What happens to potential energy when a magnetic object moves against the magnetic force?

Back

The potential energy increases.

Front

What happens to potential energy when a magnetic object moves in the same direction as the magnetic force?

Back

The potential energy decreases.

Front

What is the effect of moving a magnetic cart one space to the right towards a stationary magnet?

Back

It increases the potential energy of the system.

Front

What is the effect of moving a magnetic cart one space to the left away from a stationary magnet?

Back

It decreases the potential energy of the system.

Front

What do magnetic field lines indicate about the interaction between two magnets?

Back

They show whether the magnets will attract or repel each other.

Front

What is the relationship between distance and potential energy in a magnetic field?

Back

As the distance between two magnets increases, the potential energy decreases.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be detected.

Front

What happens to the potential energy in a system of magnets when no external forces act on them?

Back

The potential energy remains constant.

Front

What is the principle of magnetic attraction?

Back

Opposite poles of magnets attract each other, while like poles repel.

Front

How can you increase the potential energy in a magnetic system?

Back

By moving a magnet against the magnetic force of another magnet.
