The study of electromagnetic processes and characteristics systems with open magnetic core

The paper considers electric devices, based on the magnetic systems with an open core. It is usually used in various industries, in agriculture, household, transportation, medicine in the form of magnetic energy concentrators. For example, some devices can be used for water cleaning from contaminants, or as magnetic catchers in oil refinery industry, in some iron separating structures, and linear propellers [1-4, 8]. Special nozzles are used for concentrator magnetic field strengthening. The aim of the paper is to study imitation models of two electric devices structures with open magnetic system (concentrator) and hybrid magnetic system (an iron separator and a concentrator). The specific tasks include: designing the structures, their physical, mathematical and imitational models; obtaining magnetic field patterns, power characteristics as a result of physical and numerical experiments. It is shown that the hybrid model of the iron separator provides processing of substantial volume of the material being refined by the magnetic field. Numerical calculations were made by the finite element method [5-7] and with the help of ANSYS and ELCUT programmes.
