Front

What is an electromagnet?

Back

An electromagnet is a type of magnet created by electric current flowing through a wire.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the current, adding more coils of wire, or using a ferromagnetic core.

Front

What is the right-hand rule in electromagnetism?

Back

The right-hand rule helps determine the direction of the magnetic field around a current-carrying wire.

Front

What is the function of a compass?

Back

A compass is used to determine direction by aligning itself with the Earth's magnetic field.

Front

What is magnetic attraction?

Back

Magnetic attraction is the force that pulls magnetic materials toward a magnet.
