摘要

FIELD: physics.
SUBSTANCE: magnetic system comprises two residually magnetized plates enclosed in the closed magnetic circuit and fixed parallel to each other to form an air gap, made as composed by the rigidly interconnected permanent magnets. Each of them has a fixed vector module value of the magnetic moment corresponding to the estimated one, and its spatial orientation in the magnet body according to the location in the plate. On the one side, the magnetic plates are rigidly connected to the magnetic circuit. The plate for placing the magnets is divided into three concentric zones: a central zone constituting an area (Sc) at the amount of 10-15% of the total pole area (S), a peripheral zone having an area (Sp) equal to 54-60% of the S value, and an intermediate zone with an area Sint equal to the differenceSint= S-(Sc+Sp). The magnets, identical according to the magnetic moment value, are mounted in the central zone with the orientation of the residual magnetization vector perpendicular to the plate plane. The module of their vector amounts to 0.6 relative thereto of the peripheral magnets with the same orientation of the residual magnetization vector. The magnets are mounted in the intermediate zone with the module value of the residual magnetization vector equal to that of the peripheral one, but with its orientation in the magnet body toward the plate center at the angle in the range of 50÷60° against the normal to the plate plane.
EFFECT: increasing the degree of the magnetic field homogeneity in the system working area and increasing its strength.
