In an induction coil the secondary e.m.f. is
WebAn induction coil consists of a central cylindrical core of soft iron on which are wound two insulated coils: an inner or primary coil, having relatively few turns of copper wire, and a surrounding secondary coil, having a large number of turns of thinner copper wire. WebAn induction coil consists of two coils of insulated wire wound around a common iron core (M). One coil, called the primary winding (P), is made from relatively few (tens or …
