... • Does this decaying magnetic field induce an emf in the loop itself? A: Yes B: No. • Yes it does! The induced emf will be such as to produce some magnetic field to replace that which is disappearing—that is, in this case it will generate field going in through the loop, so the current will be as sh ...
