Finding out  the characteristic values and the course of the magnetic field and the modelling of this field are the principial problems of electrical engineering. In our case the magnetic field in the working area of the press machine for injection moulding of permanent magnets with anisotropic structure (powder metallurgy) is  under discussion.
 The magnetic-nonoriented mixture is injected under pressure into the working area of the press machine. The pressing tool is encircled by the field coil which is producing the magnetic field. The task of this magnetic field is to cause the  magnetic orientation of the microparticles of the pressed material in this way to produce compact permanent magnets with desired anisotropy (after pressing these semiproducts are heat treated and machined).
   Nonuniformity or nonhomogeneity of the magnetic field in the working area of the press machine cause insufficient magnetic orientation of microparticles, especially for the products with small radius of rounding off. These microparticles create nonoriented agglomerates (clusters), which after heat treatment during final machining of the semi-product are the causes of cracks or breaking off of parts of magnet and therefore they are the main cause of rejects.
   The basic precondition for reducing of rejects is the sufficient homogenous magnetic field and in this way sufficient magnetic orientation of the microparticles and minimization of the clusters creating.
   Because the  measuring of the course of the magnetic field in the working area of the press machine is very difficult or mostly impossible, our Department of electrical machines and apparatuses of Faculty of electrical engineering and informatics of VSB - Technical University of Ostrava in cooperation with the producer of permanant magnets Magnety sro., Svetla Hora   has decided  to solve this problem by means of the modelling of the magnetic field in the working area of the press machine. We use final elements method (FET) in program environment ANSYS.
   Where we found the nonhomogenities of magnetic field in the working area of the model, in the same places we experienced  cracks or even  breaking off parts of the magnets during machining.
 Then we have created models of the press tool with the aim to produce homogenous magnetic field in the working area of the press machine.
