Which mechanism disrupts superconductivity when currents exceed a limit?

💡 Explanation

Exceeding the critical current generates a large magnetic field, quenching superconductivity due to the Meissner effect disruption. This is flux penetration from surpassing the critical field, rather than thermal effects or other electron limitations, because magnetic fields directly break Cooper pairs.
