Explain about Electromagnetic induction.

Question

Accepted Answer

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field.

Electromagnetic induction is based on Faraday's law of electromagnetic induction.
It occurs when there is a change in the magnetic field strength or the relative motion between the conductor and the magnetic field.
The induced electromotive force (EMF) generates an electric current in the conductor.
Applications of electromagnetic induction include generators, transformers, and induction motors.
Examples of electromagnetic induction include a moving magnet near a coil of wire, a changing current in a coil of wire, and a rotating coil of wire in a magnetic field.
