PPT-Chapter 18.1 – Magnets and Magnetic Fields

all magnets have magnetic poles points at the ends of a magnet that have opposing magnetic qualities all magnets have a north pole and south pole that are magnetically opposite like poles repel and unlike poles attract. jlaborg Magnets Magnets Magnets Magnets Magnets and Electromagnets Electromagnets Electromagnets Electromagnets Electromagnets brPage 2br Thomas Jefferson National Accelerator Facility Office of Science Education httpeducationjlaborg Magnets and Ele 8.5 – Applications of Electric and Magnetic Fields.

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!.
