Abstract
Diametrically magnetized circular magnets are widely used in electromechanical systems, where accurate analysis of their mechanical properties is crucial for predicting responses and designing system structures. This paper proposes an approach to calculate the interacting magnetic forces of circular permanent magnets with diametrical magnetization, encompassing cylindrical and ring magnets, based on equivalent magnetizing current model. The paper provides a detailed formulation for magnetic field and force. The accuracy of the calculation results is validated through experimental measurements. The results also show richer variations in the behaviors of interacting forces between diametrical ring magnets. This study expands the selection of magnetic force calculation methods for researchers and engineers. Furthermore, the diverse behaviors identified can bring new insights for the application of diametrically magnetized circular magnets in electromechanical systems and frontier field.
