Electromagnetic induction (EMI) is the production of an electromotive force (EMF) across an electrical conductor in a changing magnetic field. It can also be described as the creation of current by moving an electric conductor through a static magnetic field.  Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Here are some examples of electromagnetic induction: Coil and magnet: When a magnet is brought towards a coil, a relative motion is generated between the two due to a... Show more
