← ScienceWhich mechanism enables zero resistance in superconducting magnets?
A)Cooper pair formation decreasing scattering✓
B)Increased electron-phonon coupling vibrations
C)Quantum tunneling suppressing electron flow
D)Enhanced spin-orbit interaction accelerating fermions
💡 Explanation
Cooper pair formation allows correlated electrons to move without scattering because the Frohlich interaction causes electrons with opposite spins to pair, therefore, resistance drops to zero, rather than creating additional electron-phonon scattering resistance.
