Electromagnetic induction means a. Charging of an electric conductor. b. Production of magnetic field due to a current flowing through a coil.

Question 4.

Electromagnetic induction means

a. Charging of an electric conductor.

b. Production of magnetic field due to a current flowing through a coil.

c. Generation of a current in a coil due to relative motion between the coil and the magnet.

d. Motion of the coil around the axle in an electric motor.


Answer:

C

When there is relative motion between coil and a magnet there is change in magnetic field lines which induces a current in the coil. This phenomenon is called electromagnetic induction discovered by Michael Faraday.
