Summary:
Magnetism is a force that causes like-charged objects to repel, and opposite-charged objects to attract. As such, it has always been a subject of fascination to scientists. As one of the fundamental universal forces, it exists in everything from asteroids to bacteria. This edition of Show Me Science describes what magnetic fields are and how they are created. The DVD also explains the Northern Lights and compares the Earth's magnetosphere to that of the sun.
