Classical eddy current losses in soft magnetic composites [PDF]

open access: yesJournal of Applied Physics, 2013
This paper deals with the problem of loss evaluation in Soft Magnetic Composites (SMCs), focusing on the classical loss component. It is known that eddy currents can flow in these granular materials at two different scales, that of the single particle (microscopic eddy currents) and that of the specimen cross-section (macroscopic eddy currents), the ...
