The phenomenon of electromagnetic induction is (a) the process of charging a body. (b) the process of generating magnetic field due to a current passing through a coil. (c) producing induced current in a coil due to relative motion between a magnet and the coil. (d) the process of rotating a coil of an electric motor.
Hence, the phenomenon of electromagnetic induction is producing induced current in a coil due to relative motion between a magnet and the coil. Hence, option (D) is correct.
