← ScienceWhich mechanism prevents Type II superconducting wires from exceeding critical fields?
A)Abrikosov vortex pinning increases✓
B)Cooper pair tunneling depletes
C)Meissner effect reduces flux
D)Flux quantization gets disturbed
💡 Explanation
Abrikosov vortex pinning prevents complete flux penetration, therefore superconductivity persists to higher fields because it locks vortices in place rather than instantly quenching the superconducting state as a result of magnetic blowout.
