WebHysteresis curve. According to the formulation of the volumetric magnetic energy density: (1.477) We conclude that the consumed energy in one loop is proportional to the cycle area shown in the Figure 1.15. Iron losses are generally calculated by using a posteriori approach, that is, they are estimated by postprocessing. Web23 jul. 2024 · The formula for the calculation of hysteresis loss is devised by Steinmetz, known as Steinmetz hysteresis law. He found that the area of hysteresis loop of a magnetic material is directly proportional to 1.6 t h power of the maximum flux density.
