the process of charging a body
the process of generating magnetic field due to a current passing through a coil
producing induced current in a coil due to relative motion between a magnet and the coil
the process of rotating a coil of an electric motor
The correct option is C producing induced current in a coil due to relative motion between a magnet and the coil. Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil. This electromotive force generates induced current.
