Magnetic particle testing, abbreviated MT, is a non-destructive testing method for detecting surface and near-surface defects in ferromagnetic materials. The test piece is magnetized, and at discontinuities stray fields arise where applied magnetic powder visibly adheres. This makes even fine cracks reliably detectable. MT is a fast, cost-effective, and very sensitive method, particularly used in the quality control of safety-critical components.
