- Magnetic powder composites find ever-wider use as active magnetic materials for magnetic cores of electric devices. Special interest is focused on dielectromagnetics. They are powder composites made from soft magnetic powder with an admixture of, dielectric in the form of resins, which both bind and isolate the soft magnetic particles. The properties of manufactured dielectromagnetics and their constancy over time is one of the main factors, which determine the use of these materials. When the factors are examined and understood, it will become possible to design magnetic cores in such a way that the predictable changes in their properties will not disqualify the electric devices in the course of their service. In this paper changes in the magnetic properties of dielectromagnetics caused by working temperature are described. The magnetic properties of dielectromagnetics of the specimens were tested after they were stored one year in ambient conditions at a constant temperature of 100°C and (comparative series) at a constant temperature of 21°C and a constant humidity of 50%. The research has shown that the effect of working temperature on the magnetic properties of the tested dielectromagnetics is small and profitable. This is a proof of the high quality of the soft magnetic powder used whose properties remain stable over temperature.
