What are the two types of magnets?

Back

Permanent magnets and temporary magnets.

What is a permanent magnet?

Back

A permanent magnet is a material that maintains its magnetic properties without the need for an external power source.

A temporary magnet is a material that acts like a magnet only when in the presence of a magnetic field.

Front

What are the two poles of a magnet?

Back

North and South.

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

How can you increase the strength of an electromagnet?

Back

By increasing the electric current, adding more coils of wire, or using a ferromagnetic core.

Front

What is the magnetic field?

Back

The magnetic field is the region around a magnet where magnetic forces can be detected.

What materials are attracted to magnets?

Back

Materials like iron, nickel, and cobalt are attracted to magnets.
