Topic > The Impact of Michael Faraday's Discoveries - 606

Research Paper: Faraday's Discoveries: Michael Faraday was the man behind the discovery of electromagnetic induction. Electromagnetic induction is the creation of an electric current using a magnetic field. Faraday's first experiment was set up by wrapping a copper wire around a block of wood in separate segments. The two coils had to be separated, he did it with wire. One of the coils was connected to a galvanometer (an instrument used to detect small electric currents), while the second coil was connected to a battery and a switch. When Faraday closed the switch there was a small and brief change in the galvanometer reading. This meant that Faraday had seen a small, terse current passing through the galvanometer circuit. Faraday observed the same effect in the galvanometer circuit when the battery circuit was turned off, except that the change was in the opposite or negative direction from the first galvanometer reading. The only problem with this experiment is that when the current passing through the battery the circuit was at a continuous rate...
