TEST Magnetic Fields and Electromagnets

Front

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

Back

The potential energy increases.

Front

How can you test how distance affects magnetic force?

Back

By measuring the strength of attraction or repulsion at different distances between two magnets.

Front

Which material is likely to result in the strongest electromagnet?

Back

Iron.

Front

What happens to the energy in a system when magnets move towards each other due to magnetic force?

Back

Some potential energy changes into kinetic energy.

Front

What is the interaction between two magnets with opposite poles?

Back

They attract each other.

Front

What is the interaction between two magnets with like poles?

Back

They repel each other.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What role does the core material play in an electromagnet?

Back

The core material affects the strength of the electromagnet.

Front

What is magnetic force?

Back

The attraction or repulsion that arises between charged particles due to their motion.

Front

What is the relationship between magnetic force and distance?

Back

Magnetic force decreases as the distance between magnets increases.
