About MPI

Non-destructive inspection of ferromagnetic materials

Magnetic Particle Inspection (MPI) is a relatively simple test method that can be applied to ferromagnetic materials including finished articles, billets, hot rolled bars, castings, and forgings. It requires magnetising the piece to be examined, applying the inspection medium or particles, and interpreting the patterns formed by the particles when they are attracted to the magnetic leakage field created by discontinuities in the part.
