Magnetic Fields Unit Test

Front

What happens when two like poles of magnets are brought close together?

Back

The magnets will repel each other.

Front

What happens when two opposite poles of magnets are brought close together?

Back

The magnets will attract each other.

Front

What is potential energy in the context of magnets?

Back

Potential energy is the stored energy in a system due to the position of the magnets relative to each other.

Front

What is kinetic energy in the context of magnets?

Back

Kinetic energy is the energy of motion that magnets have when they move.

Front

How can you increase the potential energy between two magnets?

Back

By moving the magnets closer together.

Front

Where is the magnetic force the strongest?

Back

The magnetic force is strongest where the magnetic field lines are closest together.

Front

What happens to energy when magnets move due to magnetic force?

Back

Some potential energy changes into kinetic energy.

Front

What type of energy does a stationary magnet near an electromagnet possess?

Back

Potential Energy.

Front

What is a magnetic field?

Back

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

Front

What are magnetic field lines?

Back

Magnetic field lines are imaginary lines that represent the strength and direction of a magnetic field.
