Question

The phenomenon of electromagnetic induction is
(a) the process of charging a body.
(b) the process of rotating a coil of an electric motor.
(c) the process of generating magnetic field due to a current passing
through a coil.
(d) None of the above.

What will be the answer for this question and how?​

Answer 1

Answer:

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.
