Richard Garriott demonstrates how magnets act in space using two magnets to see if, in microgravity, they interact with each other the same way they do on the surface of the Earth; if magnetic forces act at a distance; and where do they point. Magnetism is one of the fundamental forces. A magnet is a material or an object that produces a magnetic field that extends out from a magnet and can exert a force at a distance. A compass uses a magnet that can spin easily and can be used to determine directions. The Earth has a magnetic field that caused it to act like a giant magnet.
