Inductive charging with data transmission

equation of farrady

Electromagnetic induction (also known as Faraday's law of induction, named after Michael Faraday, short: induction) is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field.

Wireless energy transfer (also known as separate energy transmission, wireless power transmission or contactless power transfer) means energy is transferred from one object to another. This may involve various forms of energy, for example kinetic or electrical energy. In general it refers to an electrical structure, whose required power is not fed by cables and electrical contacts, but by electromagnetic fields or other physical mechanisms. The benefits include increased mobility, as well as the absence of electrical contacts and thereby related problems. Read more:
