This tutorial teaches the basic methods to define problems, perform calculations and to get related results. Pictures shown here are from calculations with version 3.0, but of course the tutorial can be used without any change in version 3.1 too. Tutorial 3.1 below is related to the new sorts of sensor magnets which have been introduced in version 3.1.
This tutorial shows the basic handling of the software as well as its basic characteristics. The problem which shall be teated here consists of a cylinder made of six homogenous segments of anisotropic ferrite, having a remanence induction of 0.40T each. The example below and similar problems ca be treated by use of the demo version of PS-PERMAG and for sure by the full versions 3.0 or 3.1. The additional features of both versions which are not shown here can also be learned easily by use of their extensive help system. The treatment of the new two pole sensormagnets of version 3.1 with enhanced geometric details can be studied in Tutorial 3.1
After starting PS-PERMAG a 3D model of an illustrative permanent magnet shows up on the screen. To define the above described magnet please click on the M symbol at the top symbol bar. M stands for circumferentially magnetized multipolar cylinders with homogenous magnetization in each pole. This opens an input dialog for the data input, see picture below. Here the basic data of the magnet have to be put in. Background for defining a cylindrical magnet is always a cylindrical coordinate system. This means e.g. that at half the axial length of the magnet there is always z=0. At zero angle phi=0 there always starts an outward oriented pole.
This tutorial shows the geometry input of the new sorts of two pole sensormagnets with depression and ledges, which have been added in PS-PERMAG version 3.1. The basic use of PS-PERMAG can be studied in Tutorial 3.0.
The following treats a two pole, axially magnetized sensormagnet. The geometry input of the other two new sorts of magnets, i.e. two pole diametrical and two pole axial-lateral, has to be done by the same way. First there has to be defined a basic cylinder. Depressions and ledges will be subtracted from this basic cylinder by up to four additional help volumes.
