Calculate the maximum current density in a lead wire of diameter 4 mm at a temperature of 4.2K if the wire is to remain superconducting. The relevant values for lead are Tc= 7.19k and Bc =6.39 x104 A/m . (note that the magnetic field in the wire is given by B = µ0I/2?r where r is the radius from the center of the wire.
