Abstract:

The influence of the dimensions of the inhomogeneity of the medium on the values of the secondary sources of the magnetic field is analyzed. The problem considered is solved by the Fourier method in the more general case. In the solution it was found out that it is sufficient to know the geometric relations of the ferromagnetic and non-ferromagnetic regions. It is shown that the formulas given in the literature for determining the values of the secondary field sources are obtained as a special case with the corresponding ratio of the ferromagnetic and non-ferromagnetic regions.
