Superconductivity:resistance is useless
... The ability of superconductors to carry large currents depends crucially on the response of the VL. When a current passes perpendicular to the vortices they feel a force, in the same way as a current-carrying wire in an electrical motor feels a force in a magnetic field. If there is nothing to resis ...

This induced current creates a force which resists the motion of the loop (if the loop moves), and a magnetic field opposite to the field which initially produced the flux. This essentially removes energy from the mechanical motion and reduces the energy in ...
