Hence, an e.m.f. is induced in it which is Cut-away view of dc generator D.C. Generators 889 proportional to the rate of change of flux linkages (e = NdΦdt). When the plane of the coil is at right angles to lines of flux i.e. when it is in position, 1, then flux linked with the coil is maximum but rate of change of flux linkages is minimum.
On the hand, if we use split rings, then it acts like a commutator, it keeps changing the contacts for every half a rotation and make sure that the current does not change the direction in
