WebEverything does actually have a magnetic field... But only at a microscopic/atomic level. Consider the fact that electrons are present in the atoms and are constantly revolving … WebStated simply, Faraday found that (1) a changing magnetic field in a circuit induces an electromotive force in the circuit; and (2) the magnitude of the electromotive force equals the rate at which the flux of the magnetic field through the circuit changes. The flux is a measure of how much field penetrates through the circuit.
