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.
Ampere's Law has shown us how currents, moving electric charges, can create magnetic fields. Faraday's Law has shown us how changing magnetic fields can induce an emf in a closed loop. Now we are going to reinterpret Faraday's Law to see how the changing flux induces a nonconservative electric field in a coil.otice that this induced electric field is different from an electrostatic field created by a stationary point charge. When a test charge is moved along any given equipotential surface, no work is done by these conservative fields since the electric force acts perpendicular to the surface.
