The possibility of applying a standard method for calculating the shear force for high-coercivity samarium-cobalt permanent magnets in a magnetic system in which the width of the magnet is more than two times smaller than its thickness is considered. Based on the results of the study, correction factors were introduced into the methodology for calculating the shear force in a magnetic system using such magnets depending on the air gap between them. Using the obtained mathematical expression, it is possible to calculate the shear force of permanent magnets in a magnetic system at the stage of design development of hermetic equipment when using magnets having dimensions of 2.57 (width) × 30 (length) × 8 (thickness) mm and an air gap between them from 1 to 4 mm.
