Which issue arises when applying extreme field enhancements to superconducting YBCO magnets?

💡 Explanation

Reduced pinning occurs because extreme fields lower the energy needed for flux lines to move across YBCO. This flux creep degrades superconductivity via Abrikosov vortex motion, therefore preventing stable high-field operation rather than enhancing desirable magnet behaviors given the same applied external field.
