Abstract The magnetic losses in the Fe72,5Cu1Nb2Mo1,5Si14B9 nanocrystalline alloy were investigated in a wide range of magnetic induction from 0.01 to 1.0 T and frequencies from 60 Hz to 100 kHz. Dependences of magnetic losses approximated by power function. It is shown that the exponent of the power function depends on the ratio of hysteresis losses and eddy current losses, as well as on the number of actively moving domain walls. The number of domain walls was calculated using a domain model and measured eddy current losses.
