The invention relates to the electrical industry, in particular to the design of magnetic cores and cores of electrical apparatus, relays, magnetic starters and electromagnets.

The purpose of the invention is to increase the efficiency of use by reducing the magnetization reversal and reducing the material intensity.

The magnetic circuit of the electrical apparatus is assembled in the following manner.

By alternating plates of electrical steel 5 and extruded and magnetically sintered soft material 6, the magnetic core is assembled of the required thickness and fixed with the help of rivets 7,
