The study and calculation of magnetic field of the DC electromagnet with the split poles and polar tips

Among magnetic systems of electromagnets of a direct current with polar tips, the valve magnetic system is the most widespread and well-studied due to its broad application in drives of electromagnetic switching devices, devices of automatic equipment and control. However, even at synthesis of such magnetic system of an electromagnet, developers have a problem of definition of a share of a magnetic flux under a polar tip leaving in a working gap. The solution of a task becomes even more complicated at absence of a rotary anchor in a direct current electromagnet as the magnetic field in an inter-polar gap is sharply non-uniform, fading in process of removal of the studied point from the plane of poles. Such distribution of a magnetic field takes place in special electromagnets of a direct current - suspended separator used for extraction of ferromagnetic objects from various bulks transported by tape conveyors.
