← ScienceWhich outcome occurs when operating a superconducting magnet above its critical current?
A)A quench and rapid resistance increase✓
B)Mechanical stress exceeds material yield
C)Spontaneous parametric down-conversion occurs
D)Enhanced quantum entanglement arises
💡 Explanation
A quench occurs because exceeding critical current disrupts Cooper pairs, halting lossless current flow; therefore, a rapid resistance increase and energy dissipation results, rather than other quantum effects or mechanical failures under normal circumstances due to robust material design.
