Electromagnetic Induction

What is Electromagnetic Induction?

Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using ac power source) or when a conductor is constantly moving in a stationary magnetic field.

This phenomenon was discovered by Michael Faraday. He arranged a conducting wire as per the setup given below, attached to a device to measure the voltage across the circuit. When a bar magnet was moved through the coiling, the voltage detector measures voltage in the circuit.

Answer 2

Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field
