troduction •A bit about Michael Faraday Michael Faraday was an English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis.

•Law of Electromagnetic Induction

Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon called electromagnetic induction. It is the fundamental operating principle of transformers, inductors, and many types •Faraday and his Law of electrical motors and generators. Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however, Faraday was the first to publish the results of his experiments. Faraday explained electromagnetic induction using a concept he called lines of force. These equations for electromagnetics are extremely important since they provide

•Something IMPORTANT An important aspect of the equation that quantifies Faraday’s Law comes from the work of Heinrich Lenz, a Russian physicist who made his contribution to Faraday’s Law, now known as Lenz’s Law, in 1834.
