Question

State the principle of electromagnetism

Answer 1

Answer: Principle of Electromagnetism states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.

OR

Electromagnetism is defined as an attraction between particles which is defined as created by electricity. An example of electromagnetism is the force which is the basic operation of an electric motor

Answer 2

Answer:

Faraday's Principle of Electromagnetic Induction states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.
