← ScienceWhich risk increases when operating superconducting magnets beyond critical current?
A)Sudden quenching of superconductivity✓
B)Increased resistive heating losses
C)Enhanced magnetic field homogeneity
D)Greater mechanical vibration damping
💡 Explanation
Exceeding critical current causes a breakdown of Cooper pairs. This sudden loss of superposition, causes a phase transition resulting in runaway Joule heating referred to as 'quenching' because of the Meissner effect failure, rather than increased heat resistivity or stability against vibrations.
