Abstract

The aim of this paper is to emphasize the influence of the magnetization vector misalignment to the magnetic force. In this concrete example the force between permanent ring magnet and soft magnetic cylinder was analyzed. Configuration that can be seen in different devices that incorporate permanent magnets. Magnetic force between permanent ring magnet and soft magnetic cylinder is calculated using hybrid boundary element method and semi-analytical approach based on fictitious magnetization charges. By selecting the angle of the magnetization vector inclination, obtained expression can be used for the force calculation of axially or radially magnetized permanent magnet and magnetic body of finite dimension.
