Question

about electromagnetic induction 

Answer 1

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.

Answer 2

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.
