This method involves the component under inspection being magnetized, this magnetization process is supplemented by the application of ferromagnetic particles to the already magnetized surface. The magnetic particles are attracted to areas of flux leakage (escaping magnetism) and indications formed at that point. This method is used to test welds, castings, and forgings for surface or subsurface defects.
