WebDec 28, 2020 · Faraday’s law of induction states that the induced EMF (i.e., electromotive force or voltage, denoted by the symbol E ) in a coil of wire is given by: E = −N \frac{∆ϕ}{∆t} Where ϕ is the magnetic flux (as defined above), N is the number of turns in the coil of wire (so N = 1 for a simple loop of wire) and t is time.
