Magnetic Particle Inspection (MPI, MT) is a non-destructive testing process that uses a magnetic field and iron filings to identify defects in steel, cast iron or welds. It works because the iron filings will tend to concentrate at the site of any flaw or leakage.

Depending on the application, the tester may use a wet or dry method.
