when an alternating e.m.f. is applied to the primary coil, a changing current flowing in it produces an alternating magnetic flux in it. this causes the change in magnetic flux linked with the secondary coil. an alternating e.m.f. is then induced in the secondary coil. this is called principle of mutual induction
