A superconductor has `T_c(0)=100K`. When a magnetic field of `7*5tesla` is applied, its `T_c` decreases to `75K`. For this material, one can definitely say that when

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
