Abstract: Magnetic leakage is a substantial part of Magnetic test theory. Magnetic force lines produced by magnets are invisible and the proposed theories about them are different. The leakage phenomena from a surface breaking crack is dramatically affecting the inspection process. This is where there is no sophisticated study providing influencing parameters and their effects. In this paper, a model of magnetic leakage from a surface breaking crack using distributed point source method (DPSM) is offered. The advantage of DPSM for common methods like a FEM is that the concerned number of mesh is very low and the analysis process is reduced. Also the method is very flexible for geometry changes in crack position and size. The results show that DPSM technique is capable in modeling magnetic flux leakage and is a good alternative for FEM.


Keywords: Magnetic flux leakage, DPSM, Inspection
