← ScienceWhich property change arises due to Cooper pair formation in MgB2?
A)Loss resistive heating at Tc✓
B)Increased thermal expansion coefficient below Tc
C)Reduced electron mobility at higher temperature
D)Gain magnetic permeability above Tc
💡 Explanation
Loss of resistive heating occurs because *superconductivity* enables electron flow without scattering via *Cooper pair formation*; therefore, it conducts without energy loss via resistive heating, rather than any change magnetic or thermal expansion below the critical temperature.
