would a superconducting iron core reduce energy losses, or since current in a superconductor never dissipates would a huge amount of energy just end up being stored in the superconductor, instead of it dissipating as heat? Or would the current eventually build up to the point where the superconductor can no longer act as a superconductor, the temperature rises above Tc and then the current is dissipated as heat? Just a bit curious here.

Also somewhat related, just want to make 100% sure, when resistance of a metal decreases, a higher current is induced instead of a lower voltage because the voltage is constant based on the rate of change of flux, right?

I don't think it would work

Transformers work by the principle of electromagnetic induction which requires an AC power source

Cooper pairs only form when there's a DC power source since they only travel in one direction and so they would break if an alternating current were used

Wait, isn't the whole point of a soft iron core to allow for more efficient propagation of magnetic field to allow for better electromagnetic induction. If it were a super conductor, wouldn't this meant that the Meissner effect would exclude the field, making it counter-productive to transformation?
