Why can current persist in a superconductor in the absence of any applied voltage ?

An implies that a perfect diamagnet is a supercondutor. This implies that when a super conductor is put in a magnetic field of intensity B, the magnetic field B_(s) inside the superconductor will be such that :

Electrical resistance of certain materials, known as superconductors, changes abruptly from a nonzero value of zero as their temperature is lowered below a critical temperature T_(C) (0) . An interesting property of super conductors is that their critical temperature becomes smaller than T_(C) (0) if they are placed in a magnetic field, i.e., the critical temperature T_(C) (B) is a function of the magnetic field strength B. The dependence of T_(C) (B) on B is shown in the figure. . A superconductor has T_(C) (0) = 100 K . When a magnetic field of 7.5 Tesla is applied , its T_(C) decreases to 75 K. For this material one can difinitely say that when
