Abstract

In a known magnet system, specifically for magnetic separators, having homogeneously magnetized magnet blocks arranged in circular ring shape, the magnet blocks have their magnetization directions aligned differently from one to another and established in accordance with a predetermined mathematical formula. While a magnetic field running almost uniformly over the whole region of the magnet system is thus produced, the magnet blocks are made trapezoidal in cross section and, because of the many distinct magnetization directions, require separate fabrication. Both the fabrication and the assembly of these magnet blocks are therefore relatively complicated and time-consuming. In accordance with the invention, however, the fabrication and the assembly of the magnet blocks into a magnet system are quite substantially simplified and improved by virtue of the fact that the magnet blocks (1) are made square in cross section.
