WebFaraday mainly performed three experiments for the derivation of the law. In his first experiment, he explained when the strength of a magnetic field is varied only at that point in time; a current is induced. In his second experiment, he explained that electromotive force is induced when a relative motion exists between the magnet and the coil. WebOne experiment Faraday did to demonstrate magnetic induction was to move a bar magnet through a wire coil and measure the resulting electric current through the wire. A schematic of this experiment is shown in Figure 20.33. He found that current is induced only when the magnet moves with respect to the coil.
