This article discusses a semiautomatic measurement apparatus for detection of hysteresis loops of ferromagnetic materials at various magnetization frequencies. The system is based on classical oscillography method and makes it possible to expand significantly its opportunities. This article presents the experimental results on studying magnetic properties of various specimens at +25°C and at the boiling point of liquid nitrogen (–195.75°C). Hysteresis loops have been detected at the magnetization frequencies of 50, 200, 400, and 800 Hz. The obtained results demonstrate significant temperature dependence of the magnetic parameters of specimens on temperature and frequency. [ABSTRACT FROM AUTHOR] |
