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.
