On knowing the magnetic effect created by an electric current, Faraday argued that the magnetic field can also produce the electric effect. After some attempts, he realized that such an effect can't be produced by the stationary magnet. In 1831, he could generate the electric potential (electromotive force) and electric current by the time‐varying magnetic field of a moving magnet. The phenomenon is called the induction effect. The voltage induction effect demonstrated that electricity could be generated by a purely mechanical process, converting the mechanical energy into electrical energy via the medium of the moving magnetic field. The first DC generator was demonstrated by Faraday himself, and next year French instrument maker Hippolyte Pixii built the first A.C. generator inaugurating the Electrical Age. Now, the electricity was ready to accelerate the growth of human civilization at an unprecedented rate [B.6, B.7].
