Two ideal & identical coils connected in series on the same core have equal current flowing in opposite directions. The inductances are opposing so the total inductance is zero.
If we place another coil on the core to act as a primary coil we now have a transformer, or do we?
Since the inductances are canceling each other wouldn't the voltage across the secondary coil be 0?
