KATARZYNA BLOCH, MARCIN NABIALEK, KONRAD GRUSZKA REMAGNETIZATION CORE LOSSES IN THE MASSIVE AMORPHOUS FECOYB ALLOY In this paper were studied the influence of magnetic field frequency and induction on the total core power loss – which is divided into eddy current loss, hysteresis loss and anomally losses of the bulk amorphous alloy. The total core power loss of the investigated bulk amorphous alloy increases with magnetic field frequency and peak induction. It follows a power relation similar to what has been observed in classical ribbons. In the investigated alloy in addition to losses due to magnetic hysteresis and eddy currents, other additional losses are present. However additional losses, emerging simultaneously to the component associated with migration relaxations are very weakly dependent on the frequency and temperature.
