Explanation

According to the number of critical magnetic field Hc (T), superconductors can be divided into two categories. Where there is only one Hc (T), it is called type I superconductor, that is, when Tsuperconducting state state, it has complete diamagnetism and zero resistance; When H exceeds Hc (T), the magnetic induction intensity (B) in this type of superconductor is no longer equal to zero and assumes a normal state, that is, the magnetic induction intensity is proportional to the magnetic field intensity.
