| Popis: | An interrelation is shown to be valid and grounded between the density of specific magnetic-hysteresis loss Wh and of steels measured over minor magnetic-hysteresis loops under magnetization reversal, as well as technical saturation magnetization Ms, coercive force Hcs, remanent magnetization Mrs measured over the saturation-hysteresis loop, and maximum strength of the magnetizing field Hm measured over a minor hysteresis loop. A formula is found that allows one to calculate Wh for steels based on their Ms, Hcs, Mrs, and Hm. The features of the effect of the magnetic properties of steels exerted on Wh depending on Hm are analyzed. It is established that, with increasing Hm, the changes in Mrs affect the value of Wh to a lesser extent. At the same time, the increase in Mrs always causes an increase in Wh. On the contrary, the increase in Hcs leads to increasing Wh only in the case of steel magnetization reversal in strong fields. In the case of Hm |
