Analiza pola magnetycznego w próbkach otwartych i zamkniętych magnetycznie

In the paper a measured B/H curves for magnetic specimen made of the amorphous metal ribbon are presented. Measurements were made in magnetically open and closed magnetic circuits. As closed magnetic circuit transformer under no load state was used. In the case of open magnetic circuit the cylindrical specimen was measured with using the permeameter. Thus, the magnetic flux density B and magnetic flux intensity have been measured directly. Moreover, the magnetic field distributions for the transformer have been calculated by using the Finite Element Method (FEM).
