Technical Field

Background
At present, the magnetic powder inspection method is widely applied in various fields of domestic and foreign industries, and the basic principle of the magnetic powder inspection is as follows: when a ferromagnetic material is magnetized in a magnetic field, the local magnetic permeability changes, that is, the magnetic resistance increases, due to the change of the defects or the structural states on the surface and the near surface of the material, so that the magnetic flux in a magnetic circuit is correspondingly distorted: part of the magnetic flux passes through the defect directly, part of the magnetic flux bypasses the defect inside the material, and part of the magnetic flux leaves the surface of the material, bypasses the defect through air and reenters the material, so that a leakage magnetic field is formed on the surface of the material. Generally, the deeper the surface crack, the higher the magnitude of the leakage flux out of the surface of the material, and there is a substantially linear relationship between them. At the leakage magnetic field, two poles (S, N poles) are formed at two sides of the defect due to the magnetic lines of force going in and out of the surface of the material, and if fine ferromagnetic powder is sprayed on the surface, the magnetic powder can be adsorbed at the surface leakage magnetic field to form magnetic traces, and the shape of the defect is displayed, namely the basic principle of magnetic powder detection.
