Faraday's Law of Induction is used to determine the induced electro-motive force. Electro magnetic induction is a process of production of electromotive force(emf) when an electric circuit is interacted with a magnetic field. The law was discovered by Michael Faraday. The force (emf) in any closed circuit is equal to rate of change of magnetic flux. This page provides you the Faraday's law of induction formula to find the Induced electromotive force by dividing magnetic flux with time.
