| How magnetism works |
Magnetism
- A magnet will pull some metals towards itself.
- Most metals are not attracted (not pulled) to magnets.
- The metals that are attracted to magnets are iron, nickel and cobalt. These metals are called magnetic.
- Steel is a mixture of metals. Steel is magnetic because it contains iron.
- All magnets have two poles.
- Two magnets with unlike poles facing will attract (pull towards) each other.
- Two magnets with like poles facing will repel (push away) each other.
- The pull of a magnet can be measured with a newton meter. |
