The research of the magnetic field power characteristics of a hybrid magnetic system with various concentrators

The paper discusses the design of electrical systems that are open-type hybrid magnetic systems of various configurations. The goal is: to research magnetic field and its power characteristics for electromagnetic iron separators with four magnetic field concentrators in a frustoconical and knifelike form, and to enhance and create greater inhomogeneity of the magnetic field generated in a predetermined area of space at constant power consumption. To achieve the research goal, the following tasks are solved: to develop three-dimensional mathematical and simulation models of the proposed hybrid magnetic systems; to get magnetic field patterns and its power characteristics as a result of numerical experiments. The research methods are: Maxwell's electromagnetic field theory, finite elements method (FEM), simulations using the software package ANSYS Maxwell. Findings are: there are proposed constructions of a hybrid magnetic system - iron separators with different concentrating nozzles, that allow to maintain predetermined turndown of the magnetic induction, to improve the magnetic field power characteristics of these systems, as well as a significant field inhomogeneity that results in an increase of ponderomotive forces acting on the ferromagnetic inclusions of the treated substance.
