Question

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

Answer 1

Answer: (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.
