The paper deals with the magnetic system of the disk separator with permanent magnets. It is shown that the developed magnetic system can be used to purify finely dispersed friable substances from unwanted ferromagnetic inclusions. The main advantage of the magnetic system is the ability to self-clean the surface of a non-magnetic rotating discharging disk. The research of the distribution of the force function acting on multi-domain ferromagnetic particles in the working zone of the disk separator was carried out. To solve the main tasks of the study, a finite element method was implemented, realized in the COMSOL Multiphysics software environment. It is shown that when changing the air gap or the effective length of the poles, the distribution of the force function over the height of the working zone, as well as the magnitude of force, varies. The rational size of the air interpolar gap, which provides the maximum value of power force, was determined.
