Abstract

Calculation of the interaction magnetic force between two ring permanent magnets of trapezoidal cross-section and a ring permanent magnet above the infinite linear magnetic plane is presented in this article. The simple and fast analytical approach is used for these calculations based on the distribution of microscopic surface Ampere's currents and the discretization technique. The results for the interaction magnetic force obtained using the analytical method and discretization technique are compared with the finite-element method by using FEMM 4.2 software (Meeker, n.d.).
