Which mechanism prevents flux trapping during superconducting magnet quenching?

💡 Explanation

Thermally activated flux creep allows trapped magnetic flux to slowly escape because thermal energy helps overcome pinning energy barriers. Therefore, thermally activated flux creep minimizes flux trapping effects, rather than options that affect temperature or magnetic fields.
