(1)         The current in a super conductor once set up continuous for a very long time without attenuations.

(2)        The permeability of a super conductor is 0. A super conductor is thus a perfect diamagnetic.

(3)        When the current through a super conductor is increased beyond a certain value the super conductor becomes normal.

(4)       At 0⁰K all conduction electrons, behave like super electrons, but if the temperature is raised, a few begin to behave as normal electrons, and on further heating the proportion of normal electron increases. Eventually, at the transition temperature, all the electrons become and the metal loses its super conducting properties.
