A comparative study of the intergranular current and grain conductivity of superconducting polycrystalline MgB2 wires was conducted by transport and magnetic susceptibilty measurements. The bulk intergrain critical current density was determined from measured magnetic hysteresis loops, using Bean's critical state model. Results showed strong evidence for high intergranular critical current densities and large bulk flux pinning in superconducting polycrystalline MgB2 wires.
