Which mechanism prevents ohmic heating dissipation in superconducting magnets used for MRI?

A)Meissner effect expelling magnetic fields
B)Cooper pair formation enabling conductance
C)Flux pinning preventing magnetic creep
D)Quantum Hall effect reduces resistance

💡 Explanation

Cooper pair formation causes superconductivity below a critical temperature, therefore current flows without resistance because electrons form pairs via phonon interactions, rather than single electrons scattered by lattice imperfections, creating heat.
