← ScienceWhich outcome results from exceeding quench current in superconductors?
A)Abrupt loss of superconductivity✓
B)Increased magnetic field stability
C)Enhanced flux pinning strength
D)Improved thermal conductivity locally
💡 Explanation
Exceeding quench current causes an abrupt loss of superconductivity because the **Meissner effect** collapses releasing trapped magnetic flux, creating resistive heating. Therefore, superconductivity is lost, rather than stabilized, causing local thermal rise instead being improved.
