Earth itself acts like a giant magnet, which is why compasses work.
All about Magnets
A magnet is an object that produces a magnetic field, which pulls on some metals. Magnets attract iron, nickel and cobalt. They do not pull on wood, plastic or glass.
Every magnet has two ends, called poles, labelled north and south. Opposite poles attract each other, and matching poles push apart. You can use this to test whether two magnets will stick together or repel.

Frequently asked questions about Magnets
What materials do magnets stick to?
Iron, nickel and cobalt. Most other metals, like aluminium and copper, are not attracted to magnets.
What is a magnetic field?
The invisible area around a magnet where its pull can be felt. You can see its shape by sprinkling iron filings around it.
How can you make a magnet?
Stroke a steel object in one direction with a strong magnet, or place it in a magnetic field. Some magnets are made by electricity running through coiled wire.
