In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir S.P.

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. “. Magnetic phases of spin-1 spin–orbit-coupled Bose . gases. ,”. D. L. Campbell, . R. . M. Price, .
