Question

Who gave the principle of electromagnetic induction?
(A). Volta
(B). Ampere
(C). Faraday
(D). Oersted

Answer 1

Hint: The electromagnetic induction is the relationship between the electric field and the magnetic field. When current is flowing in the conductor. The magnetic field around the conductor is developed around the conductor due to the flow of current. It is known as the electromagnetic induction.

Complete step-by-step answer:

In a conductor, when the magnetic field around it changes its electric flux continuously, the electromotive force is developed in the conductor. It implies that by changing the magnetic flux of the conductor, the electric field is developed in the electric conductor. This production of the electromagnetic force is known as the electromagnetic induction.
Michael Faraday was the first person to develop the phenomenon of electromagnetic induction. He discovered this theory in 1831. But, the mathematical relationship of “Faraday’s law” was discovered by James Maxwell.

Note: Alessandro Volta was a physicist. He belonged to Italy. He was well known as the inventor of the electrical battery. The unit of electromotive force is named after his name. The unit of electromotive force is Volt.
Andre Ampere was a physicist and a mathematician. He belonged to France. He was well known as the founder of classical electromagnetism. The unit of current is named after him. The unit of current is Ampere.
Hans Oersted was the chemist and physicist. He belonged to Danish. The Oersted law was named after him. He was well known for the discovery of electric current and magnetic fields.
