A description of the sources of magnetic field using edge values of the current vector potential

The paper discusses the method of a description of the magnetic field sources in systems with the stranded windings. The sources are determined on the basis of an obtained distribution of edge values of the current vector potential T0. The formulas describing the magnetic field sources in the finite element (FE) space for the formulations using the scalar potential F and the vector potential A have been given. The approach for determining the T0 distribution in the stranded windings of simple and complex geometries has been proposed.
