We have measured trapped field distributions by scanning a Hall probe on various rectangular YBCO bulk superconductors and studied the effects of field dependence of Jc bulk thickness and bulk size on the trapped field. The trapped field could be increased by increasing the bulk thickness and size. However, a saturation was observed for the maximum thickness. We also calculated the distribution of trapped field taking account of the field dependence of Jc. Experimental trapped field distributions were in good agreement with our calculated values when we used the Jc-B curves obtained from a d.c. magnetization measurement for samples.
