The proposed paper describes the simulations of magnetic field strength distributions for magneto--conductive material in order to be able to optimize a measurement set--up that should be capable to detect minute changes of the magnetic field strength at the surface of a specimen containing some kind of material inhomogeneities or anisotropies of magnetic properties. The sensitivity which ultimately is limited by the noise figure of the sensing effect (GMR = giant magneto resistive effect) can be evaluated with respect to the detection of deviations in eddy current patterns caused by inhomogeneities of the material's conductivity or the anisotropy of magnetic properties of the specimen's material.
