Abstract: Axial magnetic force calculation between two ring permanent magnets is presented in the paper. One magnet is magnetized in radial direction while the other one is magnetized in axial direction. Configuration like this one resembles the one passive magnetic bearing has. Force calculation is performed using semi analytical approach based on fictitious magnetization charges and discretization technique. For comparison purposes, and in order to check preciseness of the method applied, Finite Element Method (FEM) results were used. [Projekat Ministarstva nauke Republike Srbije, br. TR 33008]
