PPT-Magnetism ● An electric charge experiences a magnetic force when moving in magnetic

A moving charge produces magnetic field There are two basic ideas in our introductory study of magnetism FIRST THINGS FIRST THEIR MAJESTY THEMSELVES MAGNETS The ancient Greeks originally those near the city of Magnesia and also the early Chinese knew about strange and rare stones possibly chunks of iron ore struck by lightning with the power to attract iron A steel needle stroked with such a lodestone became magnetic as well .

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. material due to the arrangement of its atoms, particularly its electrons.. Lik. e poles will repel, opposite poles will attract.. Magnetic field lines describe the structure of magnetic fields in three dimensions.. History #1. .
