- Abstract:
-
A trapped field of over 3T has been measured at 17.5K in a magnetized stack of two disc-shaped bulk MgB superconductors of diameter 25mm and thickness 5.4mm. The bulk MgB samples were fabricated by uniaxial hot pressing, which is a readily scalable, industrial technique, to 91% of their maximum theoretical density. The macroscopic critical current density derived from the trapped field data using the Biot-Savart law is consistent with the measured local critical current density. From this we ...
