Abstract The paper presents results of investigations of powder composites made of magnetically soft iron powder and dielectric - PVC - insulating and bonding molecules of this powder. The research was done on self-developed cylindrical samples. The study was aimed to determine the effect of molding pressure and the grain size of Fe on the magnetic properties of the samples. The studies have showed that an increase in core forming pressure obtaining higher induction B values at a lower H field intensity. It was also found that better parameters were obtained in the case of samples with a larger iron particle size.

Soft Magnetic Composites

Abstract The magnetic properties of Fe-based composite materials with different particle sizes were investigated. The results of energy loss density were obtained from measurements of the static (DC) hysteresis cycles ranging from 0,2 to 1,4 T. In turn, the results of power loss density were obtained from measurements of the dynamic (AC) hysteresis cycles ranging from 20 to 400 Hz and at the maximum flux density 0,3; 0,9 and 1,3 T. Two sets of specimens was analyzed in the investigation: the specimens compacted under pressure of 800 MPa and hardened at 500°C and the specimens compacted under different pressure and hardened at 500°C. Specimens of the second set had the same density. The study confirmed the influence of particle size distribution on magnetic properties of Fe-based soft magnetic composites.
