Abstract
The paper presents a formula useful for prediction of loss density in
soft magnetic materials, which takes into account multi-scale energy
dissipation. A universal phenomenological P(Bm, f) relationship is used
for loss prediction in chosen soft magnetic materials. A bootstrap method
is used to generate additional data points, what makes it possible to
increase the prediction accuracy. A substantial accuracy improvement for
estimated model parameters is obtained in the case, when additional data
points are taken into account. The proposed description could be useful
both for device designers and researchers involved in computational
electromagnetism.
