Electromagnetic Induction

The production of a voltage in a coil because of a change in the number of magnetic lines of force passing through the coil.

The phenomenon was first investigated in 1830-31 by Joseph Henry and Michael Faraday, who discovered that when the magnetic field around an electromagnet was increased or decreased, an electric current could be detected in a separate nearby conductor.
