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 current play in an electromagnet?

Back

The strength of the magnetic field is directly proportional to the amount of current flowing through the wire.

Front

What is magnetic field strength?

Back

A measure of the intensity of the magnetic field, often represented by the symbol B.
