← ScienceWhich mechanism enables persistent current flow below critical temperature?
A)Cooper pair formation.✓
B)Increased phonon scattering.
C)Enhanced magnetic domain alignment.
D)Decreased Fermi level energy.
💡 Explanation
Superconductivity emerges because Cooper pair formation causes electrons to condense, thereby bypassing scattering events normally resisting current flow rather than phonon interaction increase or enhanced magnetisation leading other outcomes.
