PS-PERMAG

PS-PERMAG - Software for Calculating Permanent Magnetic Fields

PS-PERMAG in its current version 3.1 enables the user to do easy and fast analyses of the fields that are originated by permanent magnets. In general expensive FEM software is used for this purpose, which demands many efforts and a substantial quantity of knowledge. Such programs generally can be handled by specialists only. In contrast  the software PS-PERMAG provides the computation of 3D field distributions by simple input of the magnets dimensions, its remanence induction and its pole number. PS-PERMAG offers this for the majority of common geometric magnet layouts.
