Electromagnetic induction is the production of anelectromotive force across a conductor when it is exposed to a varying magnetic field. It is described mathematically by Faraday's law of induction, named after Michael Faraday who is generally credited with the discovery of induction in 1831.

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field.Electromagnetic Induction applied to a coil of wire. A changing magnetic flux induces a current into a coil.Electromagnetic Induction is the process of using magnetic fields to produce voltage, and in a closed circuit, a current.Oersted's surprising discovery of electromagnetism paved the way for more practical applications of electricity, it was Michael Faraday who gave us the key to the practical generation of electricity: electromagnetic induction. Faraday discovered that a voltage would be generated across a length of wire if that wire was exposed to a perpendicular magnetic field flux of changing intensity.
