Brief history about the evolution of magnetism and electricity from ancient age (600 BC) to modern usage.
Magnetism and electricity are intrinsically linked, without one we couldn’t have the other. History is littered with philosophers, physicians, engineers and inventors that have all contributed to our understanding of and the development of electricity and magnetism, many of which are detailed here in our brief history.
In 1820, Ørsted invited some colleagues over to show them the way metal could conduct an electrical current. When he fired up the current, Ørsted noticed the needle on a nearby compass moved, which he intended to use for a different demonstration. Before, nobody had ever observed a relationship between electricity and magnetism. He kept his findings secret until figured out how and why his demonstration had affected the magnetic field of the compass.
