Abstract
Determination of the critical magnetization current density of large superc onducting samples was performed using a levitation force method. It is base d on measurement of the force between the superconductor and a permanent Nd -Fe-B magnet, thus the applied magnetic field may be up to similar to 0.4 t esla. At this field, levitation forces up to 6.6 N (5.5 MN/m(3)) were measu red on melt processed tablets of Y-Ba-Cu-O material with dimensions of simi lar to 2 cm x 2 cms 0.3 cm.
