How is the back induced current in the secondary coil transferred to the primary ? I know how mutual induction occurs (and I know that a the bst possible example would be a transformer) but I don't understand how it actually occurs ( I know it,but I still can't get it) I mean I get why when current flows in primary coil ( at the instant of switching the cicuit on) there is a change in current intensity by increase and that produces changing magnetic flux which in turn affects the secondary coil and an back induced current (or e.m.f) is formed in the secondary one. Then what ? How is this "induced current" transferred to the primary coil such that it opposes the original current (in the primary) and let's current grow slowly ? I should also mention that I'm not only under advanced level , but under ordinary level too , so please I beg you try to make the answer as simple as you could ,so that I won't be lost in a labyrinth of never-ending laws , eternal thanks in advance ~
