To induce an e.m.f. in the coil

To induce an e.m.f. in a coil, the magnetic flux

The formula for induced e.m.f. in a coil due to change in magnetic flux through the coil is (here A = area of the coil, B = magnetic field)

The phase difference between the flux linkage and the induced e.m.f. in a rotating coil in a uniform magnetic field
