Originální abstrakt

The current workplace for measuring magnetization curves uses an analog fluxmeter in which small closed samples have an undesirable effect on its lowest input resistance at the lowest ranges. When measuring a quasi-static hysteresis loop, this small input resistance limits our maximum sensitivity because the measuring winding resistance affects the constant of the analog fluxmeter. At higher frequencies, the inherent inductance of the measuring winding is signifying, which limits the area of integration of the fluxmeter into the order of kHz units. Both of these undesirable properties can be eliminated with a high-quality automatic-zero separator amplifier.
