Popis: Pulsed high magnetic field generator up to 33T with a long pulsed half-width of 70ms was constructed. Effective fields of coercivity in Nd-Fe-B sintered samples were measured in the pulsed high fields. The measurement errors were estimated experimentally and also by numerical simulations using EMAG. We found errors of coercivity fields of more than 30 % in these samples and discussed on the relationship among the sample insertion gaps in the probe and the systematic errors.
