When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant.araday's Law. Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be induced in the coil. No matter how the change is produced, the voltage will be generated.
So if a coil of N turns is linked by an amount of magnetic flux, Ï then the coil has a flux linkage of NÏ and any current, (i) that flows through the coil will produce an induced magnetic flux in the opposite direction to the flow of current.he relation between the flux in the inductor and the current flowing through the inductor is given as: Ï = Li. As an inductor consists of a coil of conducting wire, this then reduces the above equation to give the self-induced emf, sometimes called the back emf induced in the coil too:
