Magnetic particle inspection (MPI) is used for the detection of surface and near-surface flaws in ferromagnetic materials. During magnetic particle inspection (MPI), a magnetic field is applied to the specimen, either locally or overall, using a permanent magnet, electromagnet, flexible cables or hand-held prods. If the material is sound while we perform magnetic particle inspection (MPI), most of the magnetic flux is concentrated below the material's surface. However, if a flaw is present during magnetic particle inspection (MPI), such that it interacts with the magnetic field, the flux is distorted locally and 'leaks' from the surface of the specimen in the region of the flaw
Fine magnetic particles, applied to the surface of the specimen, are attracted to the area of flux leakage, creating a visible indication of the flaw. The materials commonly used for magnetic particle inspection (MPI) are black iron particles and red or yellow iron oxides. In some cases, the iron particles are coated with a fluorescent material enabling them to be viewed under a UV lamp in darkened conditions. magnetic particle inspection (MPI) is a non-destructive test, and is not covered under the National Aerospace and Defense Contractors Accreditation Program (NADCAP).
