The equation for the emf induced by a change in magnetic flux is \[emf = -N \frac{\Delta \Phi}{\Delta t}.\label{23.3.1}\] This relationship is known as Faraday's law of induction. The units for emf are volts, as is usual.

Faraday’s experiments showed that the emf induced by a change in magnetic flux depends on only a few factors. First, emf is directly proportional to the change in flux Δ Φ Δ Φ . Second, emf is greatest when the change in time Δ t Δ t is smallest—that is, emf is inversely proportional to Δ t Δ t .
