Electromagnetic Induction


What is Electromagnetic Induction?

Electromagnetic induction occurs when a conductor moves through a magnetic field. It produces a voltage in the conductor, and if the conductor is part of a complete circuit it creates a current. Electromagnetic induction is primarily used within generators and motors. The generator converts mechanical energy into electrical energy. The operation of a motor is similar to that of a generator but in reverse. In a motor the electric current supplied to the loop exerts a torque, which turns the loop. The motor, therefore, converts electrical energy into mechanical energy.

Who discovered it?

Michael Faraday is usually credited with the discovery of induction in the year of 1831. Faraday's law of induction is a basic law of electromagnetism that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). It is the fundamental operating principle of transformers, inductors, and many types of electric motors, generators and solenoids.
