... not cut any magnetic field lines, so the induced emf is zero. (1M) When = 900, or 270o, the plane of coil is parallel to the field lines, its motion cuts the field lines at the fastest rate (or the rate of change of flux linkage is the greatest), thus the induced emf is a maximum. (1M) (iii) The p ...
