Development of technology and notably development of new generation magnetic materials caused substitution of cast magnets with magnets manufactured in the process of powder metallurgy. Development in magnetic materials is observed not only hard magnetic materials, but also soft magnetic materials. Particular intensive development can be observed in powder materials, which more and more often substitute traditional materials, e.g. electrical steel. The main factor deciding about application of soft magnetic elements is its magnetic properties. In many applications mechanic properties are equally important as magnetic parameters. Physical properties of materials change with the change in temperature. The main goal of research is to know changes of mechanical properties of dielectromagnetics with changes of temperature.
