← ScienceWhich mechanism causes a superconducting coil to quench rapidly?
A)Flux pinning suppressing current flow
B)Vortex motion generating heat✓
C)Cooper pair separation causing resistance
D)Critical current exceeding magnetic breakdown
💡 Explanation
The coil quenches because vortex motion dissipates energy as heat causing a transition from superconducting to normal state via resistive losses. Therefore vortex motion leads to rapid loss of superconductivity, rather than flux pinning which stabilizes the superconducting state.
