"In 1831 his original researches began to center about the relation of electricity and magnetism. ...Even as early as 1824 he had noticed the effects of a current of electricity upon a magnet. Now he found that this electrical action could be increased if the wire carrying the current was made into a coil. From that point he went on to study the push or pulling action of the coil upon the magnet, the effect of having a coil of more turns, and a way by which the coil and magnet, if free to move, could be made to move around each other. He was working out the principles that operate in today's electric motors. By 1831 he had reversed the problem... He had shown that the mere motion of the magnet within a closed-end coil was enough to set moving through the coil a small current that had not been there before. He called this new current an "induced" one and proceeded to study how the current could be increased in its quantity and intensity. The experimental results were revolutionary. The principles of induction discovered by Faraday are used today in telephones, induction coils, electric generators, transformers, the motors of electric clocks, and dozens of other pieces of electrical equipment."
