Static measurement of magnetic hysteresis loop for spring steel and vacon 11 (metal-ceramic alloy NiFeCo) materials

Abstract The paper presents the results of magnetic hysteresis measurements for the materials spring steel and metal-ceramic alloy NiFeCo (Vacon 11). A static measurement was performed over a wide range of the external field H , from -10000 to 10000 A/m for the first material and from -12600 to 12600 A/m for the second. The B - H curve, also known as the hysteresis loop was created. Based on this curve, it was determined that both materials belong to the group of magnetically semi-hard materials, with coercivity ranging from 1000 to 50000 A/m. The measurement results were compared to the theoretical predictions of the analytical Fro hlich`s model, which indicated certain deviations from the measured values, with the largest deviation being 25.53%.
