Magnets are made of a kind of metal that attracts iron. To attract means to pull toward. To repel means to push away. Anything that attracts objects with iron in them is magnetic.
Magnets come in many different sizes and shapes.
An electromagnet is an object that uses electricity to become magnetic. Electromagnets can be turned on and off. It only takes a battery, an iron nail, and some wire to make a simple electromagnet.

The Earth behaves as if there is a giant bar magnet running through its middle from pole to pole. This affects every magnetic material that comes within its reach. If you hold a magnet so that it can rotate freely, it always ends up with one end pointing to the Earth's North Pole and the other to the South Pole. This is how a compass works- the needle automatically swings to the North. The Earth's magnetism comes from its inner core of iron and nickel. The Earth's magnetic field is slightly tilted, so compasses do not swing exactly toward the North Pole, but to a point a little little way off from northern Canada. This direction is known as magnetic north.
A temporary magnet is a magnet that will only be magnetic for a short time. If you take a nail and rub it against a magnet, the nail becomes a temporary magnet.
