Front

What is a magnet?

Back

An object that produces a magnetic field and has a North and South pole.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism, while temporary magnets only exhibit magnetic properties when in a magnetic field.

Front

What is an electromagnet?

Back

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

Front

What is the right-hand rule in magnetism?

Back

A method to determine the direction of the magnetic force, where the thumb points in the direction of current and fingers curl in the direction of the magnetic field.
