ABSTRACT
This chapter explains electromagnetic induction, Michael Faraday's laws, Heinrich Friedrich Emil Lenz's law and John Ambrose Fleming's rule and develops various calculations to help understanding of the concepts. It discusses Faraday's laws of electromagnetic induction. The chapter provides understand how an electromotive force may be induced in a conductor. Electromagnetic induction is the production of a potential difference across a conductor when it is exposed to a varying magnetic field. Faraday is generally credited with the discovery of induction in the 1830s. Faraday's law of induction is a basic law of electromagnetism that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force. Alternating current (a.c.) generators use Faraday's law to produce rotation and thus convert electrical and magnetic energy into rotational kinetic energy. A.c. from the primary coil moves quickly back and forth across the secondary coil. The moving magnetic field caused by the changing field induces a current in the secondary coil.
