Explanation

Superconductors have two basic characteristics: zero resistance and Meissner effect. If any parameter in temperature, magnetic field and current exceeds the critical value, superconductors will lose superconductivity and become normal conductors, which is called quench. Keep the working temperature of the superconductor unchanged. Only when the current flowing through the superconductor drops below the critical current, can the superconductor return to the superconducting state state stably. quench is usually used to indicate the phenomenon that superconducting magnet system loses superconductivity of its superconducting wire rod due to high excitation current or temperature.
