This non-destructive testing method is used for the detection of surface and near-to-surface discontinuities in ferromagnetic materials. Magnetic particle examination is generally performed on welds, crane hooks, shafts, stress areas of lifting devices or any other ferromagnetic specimen which may have cause for concern at its surface or near-to-surface. A variety of magnetic particle methods are employed such as dry powder, wet colour contrast, or wet flourescent.
