Explanation
According to the number of critical magnetic field Hc (T), superconductors can be divided into two categories. There are two Hc (T), namely the lower critical magnetic field Hc1 (T) and the upper critical magnetic field Hc2 (T), which are called type II superconductor. At the temperature lower than Tc, when the external magnetic field is less than Hcl, the superconductor, like the type I superconductor, shows zero resistance and complete diamagnetism.
