[QUOTE="Narayanan KR, post: 6419991, member: 551755"] [B]TL;DR Summary:[/B] Is the superconductor in meissner effect able to completely repel external magnetic fields because it provides large magnetic reluctance(small permeability) thereby forcing the external flux to chose alternate paths of low reluctance as shown in case 1 electrical equivalent or is it because an equal and opposite field gets produced by current loops inside the superconductor(T<Tc) as shown by case 2 circuit If it is case 2 then can this reaction field be harnessed by a coil for electricity ? [ATTACH type="full" alt="meissner1.jpg"]272879[/ATTACH] One more thing i forgot to add, is magnetic permeability of a metal constant irrespective of its temperature including superconducting temperature ?
