For the calculation of magnetostatic fields in inhomogeneous magnetized media, the use of integral equations of the second kind with respect to the density of fictitious magnetic charges in the volume and on the interfaces of the sections of the medium is effective [1-3].
The goal of the work is use of electrostatic analogy for testing the algorithm for the numerical solution of the integral equation for the surface density of fictitious magnetic charges at the interfaces of homogeneous regions of a piecewise homogeneous magnetized medium in the case of a plane meridian magnetostatic field.

Moreover, since the sample is fairly long in the strain direction, the effect of magnetostatics would be minimal.
The associated equation of motion yields the Poisson equation for magnetostatic potentials.
12) is the Poisson equation for magnetostatic potentials that contains all of classical magnetism.
However, magnetostatics of real magnets indicates that the simple linear relationship breaks down as soon as the material is not homogeneous; thus, the infinity just mentioned is removed since any real material necessarily is inhomogeneous in some way.
The goal of the work is analysis of the correctness of the application in the electrostatic analogy of magnetostatics of inhomogeneous magnetizing media of two known models of magnetization.

Some of the problems considered come from ground-water flow applications [5, 6, 11, 16, 23, 25], Stokes flow [9, 26, 24, 14, 10], elasticity [15, 2, 18, 8, 20], magnetostatics [21, 22] etc.
