DC compensated permeameter - the accuracy study

Petr Kašpar – Pavel Ripka – Jan Vyhnánek

   We describe D-permeameter originally designed by Trnka and later improved by Fajt and Kaspar and we analyze its precision for the measurement of different soft magnetic materials. The device measures DC hysteresis loops using compensation method, so that H and B can be calculated from the magnetization and compensation currents. The differences from results obtained by other standard methods are below 2 %.

Keywords: permeameter, BH curve measurement
