A magnet system having a magnet coil surrounded by a magnet pot is provided, the magnet coil being electrically connected to contact prongs, an interspace being formed between the outside of the magnet coil and the inside of the magnet pot, in which interspace a free-flowing compound is cast. The magnet coil is surrounded by a thin-walled coil insulating frame on which tubular contact guide elements are integrally molded. The thin-walled coil insulating frame is made of a thermally stable plastic material mixed with mineral fillers.

A sintered, magnetically soft composite is proposed, especially for use in solenoid valves, and a process for producing such a composite, in which initially a starting mixture from which the magnetically soft composite is formed after sintering is produced, having a ferromagnetic, especially powdery first starting component ( ) as main constituent, and a ferritic second starting component ( ) as secondary constituent, as well as possibly a pressing aid. After the starting mixture is sintered, the second starting component ( ) is present in the produced composite at least largely as grain boundary phase. The proposed manufacturing process includes the process steps: provision of the starting mixture; mixing of the starting mixture; compression of the starting mixture in a cavity mold under increased pressure; removal of the binder from the compressed starting mixture; and sintering of the compressed starting mixture to form the composite.
