This difference is ultimately due to the fact that a magnetic field, unlike an electric
field, does no work on charges moving in it (since the force acting on a charge is
perpendicular to its velocity). Hence, to calculate the change in the energy of the
...

If a superconductor is a simply-connected body, then no steady distribution of
surface currents on it can exist in the absence of an external magnetic field. This
can be seen as follows. The surface currents would produce in the surrounding ...
