The concept of electricity cannot be complete without Faraday’s Law of induction. It describes how changing magnetic fields can cause electric current to flow in a conductor.
The working principles of electric motors, transformers, generators, are all based on Faraday’s Law of Induction.
Faraday discovered electromagnetic induction in 1831. He had conducted many experiments before concluding his theory. He experimented with magnetic fields that stayed the same, and realized that they do not induce current. Then he experimented by changing magnetic fields, and saw that they induced current and voltage.
Faraday’s discovery of electromagnetic induction did not receive much acceptance from scientists when it was introduced. But Scottish scientist James Clerk Maxwell realized its importance, and used the ideas as the basis of his quantitative electromagnetic theory.
