| The phenomenon of magnetic viscosity can be observed when measuring losses on remagnetization. During magnetization of a ferromagnetic with alternating current, apart from the losses caused by magnetization and eddy currents, an additional component can be observed, which is referred to as additional losses. Such losses can be divided into two groups, i.e., strongly and weakly dependent on frequency and temperature. The paper presents tests of losses in the frequency range from 50 to 1000 Hz. Exact calculations of the share of additional losses caused by magnetic viscosity were made. |
