In 1269, Pierre de Maricourt of France found that the directions of a needle near a spherical natural magnet formed lines that encircled the sphere and passed through two points diametrically opposite each other, which he called the poles of the magnet. Subsequent experiments showed that every magnet, regardless of its shape, has two poles, called North (N) and (S) poles, that exert forces on other magnetic poles similar to the way electric charges exert forces on one another. That is, like poles (N-N or S-S) repel each other, and opposite poles (N-S) attract each other. Crane Video. What do you know about magnetism?. Electricity and magnetism are related!.
