• A. C. Dynamo also work on Electromagnetic Induction.
• When an induced current is produced because of voltage production (electromotive force) due to a changing magnetic field, it is called Electromagnetic Induction. 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.
