Simulation of the Force Characteristic of the “Coil-Permanent Magnet” System in the Presence of Ferromagnetic Elements

摘要

In this article, an integral mathematical model was obtained for calculating the force, which acts on a permanent magnet or ferromagnetic body in systems with axial symmetry. The case of constant currents in the system is considered. This mathematical model can be extended to the presence of alternating currents and the influence of motion on the electromagnetic process. which will be discussed in the following publications. The adequacy of the obtained models is confirmed by comparing the intermediate results with the solution of finite element methods. The obtained simulation results will allow analyzing the distribution of forces acting in the system. and to solve the problems of synthesis of magnetic systems with given characteristics. It is shown that the problem of calculating the components of the magnetic field induction vector in the presence of permanent magnets and ferromagnetic elements can be rather complicated and requires an understanding of the processes occurring in the system.
