Magnetism

Magnetism is one of the main forces of nature. Another force of nature is gravity. Magnetism causes magnetized objects to be attracted to each other.

An example of the force of magnetism is the magnet from your kitchen which sticks to the refrigerator door.

On Earth, a simple compass can always be used to detect a magnetic field of the earth around you, and any other nearby magnetic field.

Planetary Magnets

The Earth has a dipole magnetic field. This is when magnetic field lines point in a direction out of the South Pole and into the North Pole. Planets can also have quadrupoles (4 poles) and octupoles (8-poles)....more
