high saturation magnetic flux density of B800A ·m, = 1.22 T under the optimum performance with annealing at 535C , the optimum values of core loss have reached P5 ·10k = 5.6W / kg, P5 ·20k= 17.4W / kg, P5· 50k = 80W / kg.
The core loss spectrum P(f) of soft magnetic alloy with constant permeability has been studied. It is found that P(f) has the fractal structure. The effect of the induced anisotropy energy K_u on the fractal dimension D_f is discussed

A ratio named KD is introduced and defined as the ratio of core loss under rectangular waveform excitation to that of under sinusoidal waveform excitation supposed both of which are under the same frequency and the same flux density.
-It is well known that electrical logs of boreholes can play a signi|fi|cant role in base metal exploration in identifying mineralised zones, especially when there is core loss or the borehole diameter is small or if drilling is by percussion.
The core loss increased by the eddy current loss through the laminations was 78% of all deterioration by interlocking.
Magnetic deteriorations by interlocking was caused by the core loss increased by the obstruction of magnetic flux flows and eddy current loss through the laminations.
Core loss of the test specimens declined for zirconium contents of 0.01 wt.%, whereas the magnetic induction did not change due to the addition of zirconium less than 0.133 wt.%.
Also, because of its low eddy current loss, it has good high-frequency magnetic properties, 90 W/kg core loss when measured at 400 Hz and at an induction of 1.5 T.
