Purpose: The main aim of this study is the producing of toroidal shape soft magnetic composite cores from nanocrystalline Fe73,5Si13,5Nb3Cu1B9 and Fe powders insulated with epoxy resin and to investigate the density and content of powder response of the soft magnetic properties. Design/methodology/approach: Examination of magnetic properties of SMC was made on the Ferrometr device. The magnetic parameters were determined from hysteresis loops, permeability as a function of applied magnetic field and core losses as a function of magnetic induction characteristics. Findings: The results of experimental studies demonstrated a correlation between the increase density and the improvement of the magnetic properties of the composite. Research limitations/implications: The measurements of magnetic permeability should be conducted in a wide range of frequency. Practical implications: The usability of composite cores as inductive component in electronic industry depends upon further investigations. Originality/value: Soft magnetic composites based on iron powders are essential elements in today’s electronic world. As far as we know, composites materials based on nanocrystalline material as soft magnetic materials have not been examined yet.
