Correct option is B
Sol: The correct answer is (b) Michael Faraday
Key Points:
- Electromagnetic Induction is the process by which a changing magnetic field induces an electric current in a conductor.
- This phenomenon was discovered by Michael Faraday in 1831. He demonstrated that when a magnetic field around a conductor changes, an electromotive force (EMF) is induced in the conductor.
- This discovery forms the basis for modern electric generators, transformers, and many other electrical devices.
Information booster:
- Isaac Newton: Known for the laws of motion and universal gravitation, not related to electromagnetic induction.
- Alessandro Volta: Invented the electric battery but did not discover electromagnetic induction.
- Albert Einstein: Known for the theory of relativity and contributions to quantum mechanics, not electromagnetic induction.

turns per meter. At the centre of the solenoid a coil of 100 turns and radius 0.01 m is placed with is axis coinciding with the solenoid axis. The current in the solenoid reduces at a constant rate to 0 A from 4 A in 0.05 s. If the resistance of the coil is
then the total charge flowing through the coil during this time is ____________.
