ELECTRO MAGNETIC INDUCTION

What is EMI? EMI is a phenomenon in which an electric current or electromotive force is induced in the coil due to a magnetic field produced in the coil. Michael Faraday is the scientist behind the invention of electromagnetic induction. Though Faraday was first to publish this but it was discovered autonomously by Joseph Henry. This electromagnetic induction is dependent on Faradays Laws of a magnetic field. Faraday first proved this electromagnetic theory by winding copper wires to both ends of the iron rod. He explained this theory using a concept of lines of force. What is Faradays experiment? Faraday
