Inverse magnetostatic problem for ferromagnets
We consider the problem of multi-parameter analysis of the magnetic microtopology to determine the structure of the material and finding defects.

| Summary: | We consider the problem of multi-parameter analysis of the magnetic microtopology to determine the structure of the material and finding defects. We propose a method for the analysis of raw data by dividing the obtained information on a priori criteria, determined by the physical model of a ferromagnet. We show the integral connection between the slowly varying magnetization and the stray field with tensor system functions. We calculate limits of heterogeneity of the magnetization and the external field. The analysis of experimental data for magnetic microtopology steel flat specimens with artificially created defect. The above approach to magnetostatic problem can be used in the microarray analysis and inspection. |
