Webb26 juli 2024 · The shape and size of the hysteresis loop depends upon the nature of the material. The choice of a magnetic material for a particular application depends upon the shape and size of the hysteresis loop. Consider the following cases of hysteresis loop to understand it importance − Webblat has the shape of the P(E) loop (Fig.2a). The shape of the contribution of the second term, ∆d =2QP lat χdo m, is very different from that of the first contribution. This term vanishes at the saturated tips of the loop where χdo m = 0 because of the absence of domain walls at the saturation. It also vanishes at the remanence where P lat ...

Webb1 dec. 2002 · A hysteresis loop is formed when the temperature of the sample is changed in a cyclic way through the martensitic transformation. Fig. 2 shows a set of typical … Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Plots of a single component of the moment often form a loop or hysteresis curve, where there are different values of one variable depending on the direction of change of an…
