Magnetism: a force that acts on moving electric charge and magnetic materials that are near a magnet. A magnet is anything that attracts other things made of iron, steel, and certain other metals. Each magnet has an invisible field around it. The MAGNETIC FIELD goes out in all directions. Each magnet field depends on the shape of the magnet. The field is strongest at each end or the poles.

The Earth’s magnetic field is actually weakening, and has been for the last 160 years. Magnetic fields are created by electric currents, and can also be created by moving electrons and charged particles. A new type of magnet has been discovered that is made up of a combination of iron and carbon atoms, called carbonyl iron. All magnets have two poles, a north-seeking and a south-seeking pole.

The Earth behaves like a large magnet. The magnetic north pole is located in Canada about 600 mi away from the north pole. The magnetic south pole is located in the Southern Ocean near Antarctica. The Earths outer core is made of material so hot that electric currents flow through it and create a magnetic field. A compass is pulled by the imaginary line to the north and south poles to point you north or south. If a compass is close to a magnet it will not work.
