1: Faraday's law states that a changing magnetic flux induces a voltage.
2: Voltage is the integral of E field with distance.
3: In a superconductor, or equivalently an with idealized wires having 0 resistance, there can't be any electric field inside. Thus, voltage in a superconductor should always be 0.
My question: how is it possible that Faraday's law induces a voltage in superconductors? I know it does, but I don't understand how it is possible.
Can there be some E fields during brief instants in superconductors? During the variation of magnetic flux?
