← ScienceWhich outcome arises from electron movement at superconductive critical current?
A)Flux quantization within superconducting rings✓
B)Increased electron-phonon scattering rates
C)Suppressed Cooper pair formation locally
D)Enhanced magnetic field penetration depth
💡 Explanation
Flux quantization occurs because the phase of the Cooper pair wavefunction must be single-valued around any closed loop in a superconductor; therefore, magnetic flux is quantized in units Φ₀ = h/2e, rather than other alterations stemming from exceeding critical current.
