The student Faraday completed with mercury a conductive metal, composed of two bowls, so that it had an electric wire coming out of its bottom. In one of the cups, the scientist fixed a magnetized bar vertically and in the other, he loosened another magneto. So in the first cup, in the instant that the electric wire hanging above hers came in contact with 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. Thus, this can be considered as the first electric type engine, being the ancestor of the machines designed today.
Decades later, Faraday was able to conclude that if he placed a magnet inside a coil, in which the wire passed electric power dart 125dv, it would move along the lines of force.
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.
