Suppose I had two air core electromagnets wound in a bucking configuration (ie North poles opposing each other) and they are also tightly coupled. Also assume it is 12 volts pushing the current through both electromagnets. If I was to terminate the current to one of the electromagnets very quickly obviously that same electromagnet would induce a massive voltage as part of its inductive reactance. Assuming my components were able to sustain this voltage spike without failing, what would likely happen to the current flow in the other electromagnet? It would seem that the voltage induced by the electomagnet who had its current terminated would also temporarily terminate or substantially reduce the current flow through the other electromagnet. But on the other hand in a field coil excited alternator the exciter current doesnt seem to change in magnitude even though it is in the presence of strong changing and opposing magnetic fields which result from current flow in the pickup coils. Any magnetic experts willing to offer their insights? Or maybe some good resources to check.
