Faraday's Law of Electromagnetic Induction

Faraday’s Law of Electromagnetic Induction

Electromagnetic induction Moving the magnet around the inductor will change the magnetic field inside the inductor, which will cause current to flow through the inductor. This phenomenon is called electromagnetic induction. The…
