Niobium metal becomes a superconductor (with zero electrical resistance) when cooled below 4.5 K. The permeabilty of free space is 1.25664 x 10-6 N/A?. If superconductivity is destroyed when the surface magnetic field exceeds 0.06 T, deter- mine the maximum current a 1.8 mm diame- ter niobium wire can carry and remain super- conducting. Answer in units of A.
