Magnetic Fields Review

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected. It is represented by field lines that show the direction and strength of the magnetic force.

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

Back

They repel each other.

Front

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

Back

They 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 are moving due to magnetic forces.

Front

How can potential energy be converted to kinetic energy in a system of magnets?

Back

When magnets are moved closer together or further apart, some of the potential energy is converted into kinetic energy as they move.

Front

What is the role of magnetic field lines?

Back

Magnetic field lines visually represent the strength and direction of a magnetic field. The closer the lines, the stronger the magnetic field.

Front

What does it mean for magnets to attract?

Back

Attraction occurs when opposite poles of magnets come together, pulling each other closer.

Front

What does it mean for magnets to repel?

Back

Repulsion occurs when like poles of magnets push each other away.

Front

How does distance affect the strength of a magnetic field?

Back

The strength of a magnetic field decreases with increasing distance from the magnet.
