Who gave the principle of electromagnetic induction?

Michael Faraday was a scientist who contributed to the study of electromagnetism. His main discoveries include the underlying electromagnetic induction, diamagnetism, and electrolysis. His breakthrough came when he wrapped two insulated coils of wire around an iron ring and found that upon passing a current through one coil a momentary current was induced in the other coil. This phenomenon is now known as induction. In subsequent experiments, he found that if he moved a magnet through a loop of wire an electric current flowed in that wire. The current also flowed if the loop was moved over a stationary magnet.
