Magnetic hysteresis experiment

Web20 okt. 2024 · Hysteresis occurs in different substances due to the 2 different factors first one is magnetization of the material and second is the variation in the quantity of the magnetic domains of the material (it is the part of any magnetic substance where the magnetization is uniform). Web8 jun. 2024 · 2 The Basics of Magnetic Hysteresis. Measurement of a magnetic hysteresis loop begins by first saturating the magnetic moment (M) of a specimen in large positive (or negative) field (B). The intensity of the field is decreased to zero and increased in the opposite direction to negative (or positive) saturation (blue branch in Figure 1).
