Ihe intergrain critical current densities, J , parallel and perpendicular to c-axis were measured as a function of the magnetic field at 4.2 and 77.3K by an ac inductive method for the fairly oriented Bi 1 6PbO 4Sr2ca2CuPy specimens. 'Ihe J 's perpendicular to c-axis were higher than those parallel"
BiPbSrCaCuO silver sheathed high T c superconducting wires were fabricated through the solid reaction process. It is proposed in this paper that the magnetic field dependence of Jc of the wire is dominated by the Lorentz force perpendicular to the c-axis, caused by a transport current with c-axis co
