How does a generator use electromagnetic induction?

anonymous · Answer

There is a motor in a generator which carries out this electromagnetic induction,as we switch on the generator the magnetic field lines between that motor get cuts off by the rotating coil which cause change in flux and change in flux cause induced emf,cue to emf at different points of coil cause current to get flow and then generator will get on.
