Steady-State Magnetic Field Computing By Using the Integral Model of Molecular Currents

Abstract

The issue of magnetic field in a media where the magnetic permeability is defined as a function of point is not a simple one. In this paper is presented a computing method of steady-state magnetic field, in this type of media, that using a mathematical model of integral equations on the boundary. This model corresponds to a physical equivalent and is using, in this sense, fictive repartitions of the density of sources, on the boundary, as fictive currents (molecular currents). The physical premises for this kind of equivalent are represented by the magnetizing of magnetic bodies introduced in an exterior magnetic filed.
