Abstract

In this paper a procedure for magnetic hysteresis measurement in quasi-static regime with a controlled rate of change of the magnetic polarization is proposed. The waveform of the polarization is modulated by means of iterative augmentation using an inverse approach. The setup, the measurement principle and the logical diagram of the procedure algorithm are presented. Experimental results obtained with the new procedure, applied on soft magnetic materials are presented. The measurements made at 0.1 Hz and 1 Hz show a difference of the characteristic values in the range of 5 % to 8 %. The paper demonstrates that, with this new procedure, quicker and more reliable measurements could be obtained.
