Which 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.
