Do you know, when the electric machine had been made? In 1831, the scientist Michael faraday discovered that a mechanical motion was introduced to move a closed circuit conductor in magnetic field, an electrical voltage was somehow produced that caused a current to flow. Some scholar have gone so far as to say that this was the most important scientific discovery of all time! Even is this is not accepted, it has proved to be one of primary discoveries of scientific history. All motor and generator depend directly on the applied use of discovery.
Couple with faraday’s discovery was the already know fact that magnetism could be generated by electric current passing trough a coil. It was known that like magnetic pole repelled each other and unlike pole attracted each other. Together, these phenomena, ruled by other electrical laws have made motors and generators possible
