Determination of the degree of easy axis alignment in uniaxial permanent magnets from remanence measurements

The possibility of applying the standard calculation of the shear force of thin high-coercive neodymium— iron—boron permanent magnets in magnetic systems and magnetic couplings is considered. A correction factor is proposed for calculating the shear force in systems with thin magnets, which allows at the stage of developing sealed equipment to calculate the shear force of permanent magnets in these systems.

The article considers the possibility of applying a standard method for calculating the repulsive force for a thick high-coercive permanent magnets from samarium-cobalt alloy in a magnetic system. The results of the research allowed us to introduce correction coefficients in the method of calculating the repulsive force in a magnetic system with such magnets, depending on the air gap between of them. It is shown that the repulsive forces of the North poles of permanent magnets differ from the repulsive forces of the South poles. The research was carried out with magnets manufactured by different enterprises. When calculating the repulsive force, the average value of the repulsive force between the North and South poles of magnets is found.
