It is possible to say that among the scientists who contributed to the experiments on the connection between electricity and magnetism was the Englishman Michael Faraday. Born near London, he was both physicist and chemist, although he had a weak theoretical background. Therefore, he valued experiences as evidence of natural phenomena. Faraday filled with mercury a conducting metal, formed by two bowls, so that it had an electric wire coming out of its bottom. In one of them, he fixed a magnetized bar vertically and in the other, he loosened another magneto.
In the first cup, the moment the electric wire hung above hers touched the mercury, closing the circuit, it began to spin around the magnet. In the other cup, where the wire was loose, at the moment it was connected to the current, the magnet revolved around the central wire. So this was the first electric-type engine mrosupply motors, the authentic ancestor of the machines designed today. Some time later, Faraday was able to conclude that if he placed a magnet inside a coil, in which the wire passed electric power, it would move along the lines of force.
