Abstract :A practical magnetic measurement system for use in the research of Goss-oriented silicon-iron sheet, which is built compactly based on the interconnection of digitizing oscilloscope with personal computer, is prcsented. In tl1is system, it was intended to expand the frequency range of power loss measurement down to 10 Hz keeping a good accuracy for the purpose of separating the hysteresis loss and eddy current loss, because this is necessary in researching low core loss materials. The point espe­cially paid attention to for this purpose was the phase and amplitude errors of the integrating circuit which is used both for B-coil and H-coil outputs. It was shown that required measuring accuracy can be kept in the frequency range 10-500 Hz by adopting a suitable integrating circuit and by optimizing the circuit parameters.
