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.

Front

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 move due to magnetic forces.

Front

How does the distance between two magnets affect the magnetic force?

Back

The magnetic force decreases as the distance between the magnets increases.

Front

What is the principle of conservation of energy in a magnetic system?

Back

Energy cannot be created or destroyed; it can only be transformed from potential energy to kinetic energy and vice versa.

Front

What is the effect of moving a magnet against the magnetic force?

Back

It increases the potential energy of the system.

Front

What is the effect of moving a magnet in the same direction as the magnetic force?

Back

It decreases the potential energy of the system.

Front

What is the relationship between potential energy and kinetic energy in a magnetic system?

Back

Some potential energy is converted to kinetic energy when magnets move.
