← ScienceWhich outcome occurs when exceeding magnetic critical field strength for superconducting electromagnet coils?
A)Quench causes abrupt resistance increase✓
B)Persistent magnetic field generation continues
C)Improved field homogenization results instantly
D)Flux pinning enhances coil performance
💡 Explanation
Exceeding the critical magnetic field causes a quench because the Meissner effect breaks down, resulting in an abrupt return to normal resistance. Therefore, coil quenching occurs rather than enhanced performance because superconductivity is destroyed above that limit.
