Summary. Faraday's law of induction states that the emfinduced by a change in magnetic flux is \(\text{emf}=-N\cfrac{\Delta \Phi }{\Delta t}\) when flux changes by \(\Delta \Phi \) in a time \(\Delta t\).. If emf is induced in a coil, \(N\) is its number of turns. The minus sign means that the emf creates a current \(I\) and magnetic field \(B\) that oppose the change in flux \(\Delta \Phi.
