Magnetic detection principle: magnetic particle inspection is made of steel and other artifacts to be magnetized magnetic material, the use of the defective portion of its magnetic characteristics can absorb, depending on the distribution of magnetic particle inspection method is to detect the object display surface defects and near-surface defects. The object to be measured is placed in a strong magnetic field or by making a large current magnetization, if there are defects (cracks, folds, inclusions, etc.) exist near the surface of the object or surface, since they are non-ferromagnetic, the resistance of the magnetic field lines by the very large, magnetic field lines in the vicinity of these defects produce magnetic flux leakage. When good magnetic permeability (usually magnetic iron oxide powder) is applied to the object, the defect will suck nearby magnetic leakage field, stacking a visible magnetic track marks, so the defect is displayed (as shown above ). Magnetic particle inspection method is simple, intuitive display. When the normal direction of the magnetic field lines and defects is greater than 45 degrees, the defects can be effectively displayed. Thus, if desired magnetic detection, two mutually 90-degree direction, the magnetic field lines to ensure that all valid defect display. For gear parts, with circumferential magnetization electric induction method (non-through hole in the workpiece) or wear bar induction method (a through hole in the workpiece), the longitudinal magnetization method using induction coils. Defect when magnetized in two directions simultaneously, rotating magnetic field, to ensure the effective display all directions.
