← ScienceWhich mechanism enables lossless current flow in superconducting magnets?
A)Cooper pair formation avoids scattering✓
B)Increased electron-phonon interactions stabilize
C)Ferromagnetic domains align coherently
D)Semiconductor doping increases carrier mobility
💡 Explanation
Superconducting magnets exploit zero resistance due to Cooper pair formation, where electrons pair up, mediated by phonons. Consequently, applied current flows without energy loss due to scattering, therefore avoiding resistive heating, rather than increased scattering or ferromagnetism.
