Define electromagnetic induction ?
The concept used: Electromagnetic Induction
An electric current could be produced in a circuit by a changing magnetic field. This phenomenon is called electromagnetic induction. The phenomenon of producing an electric current in a conductor by moving it perpendicular to a magnetic field or vice-versa is called. electromagnetic induction. The current produced in the conductor is called induced current. The electromotive force (or voltage) so produced is called induced emf (or induced electromagnetic force).
