WebElectromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing 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. WebThe inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency ( X L ) as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor.
