ABSTRACT:
Magnetic-technical systems useful in magnetic separators for separating magnetic materials from liquid or dry materials containing magnetic particles. The magnetic technical systems are characterized by possessing one magnetic circuit comprising at least two magnets and at least one operating air gap, and being further characterized by the fact that the circuit containing the magnets is closed and that within said circuit there is an operating gap in relation to two mild iron or steel parts which in each case are arranged between two interconnected homopolar magnets.
