Question

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 1

⭐⭐⭐Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.⭐⭐⭐

Answer 2

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

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