Magnetism

Magnetism 

This is the invisible force of attraction or repulsion between objects made of iron, steel or nickel.

Magnets have a North Pole and a South Pole.

Like poles repel and unlike poles attract.

The region of force around a magnet is called the magnetic field.

The North Pole of a magnet always points to the north of the earth.

The South Pole always points to the south.

What is a compass?

An instrument that helps people use the earth’s magnetism to find direction. A compass needle behaves just like a needle magnet and always points to the north of the earth.
