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.
