Which mechanism enables induced current flow when cooling niobium-titanium alloys?

A)Cooper pair formation
B)Phonon-electron interaction
C)Fermi level stabilization
D)Magnetic flux quantization

💡 Explanation

Cooling niobium-titanium allows electrons to form linked pairs. The process of Cooper pair formation lets them move without resistance, because the electron-lattice-electron interaction binds them; therefore, induced current flows with no applied voltage, rather than ohmic resistance as a metal.
