We have coil connected to dc supply and a secondary coil connected to load. We cross the secondary coil with the primary and emf of mutual inductance is induced at that verry moment. Then the induction stops for there is no more change in the flux.
However, if an emf is induced in the 2coil there will be current witch will create magnetic field wich will cross the primary coil and by Lenz law will induce in it emf that will create another magnetic field that will continue this circle for ever. But thats not what happens. So my question is what heppens?
