Explanation
The minimum magnetic induction intensity required to transform a superconductor into a normal conductor at a certain temperature is related to the temperature of the superconductor. The lower the temperature, the greater the critical magnetic field. There is a critical magnetic field in the type I superconductor, and there are two magnetic fields, lower critical and upper critical, in the type II superconductor.
