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.
