[0002] Magnetic particle testing, also known as magnetic particle inspection, or MT for short, is a method of applying a magnetic field to the workpiece to magnetize it (whole magnetization or local magnetization). Magnetic lines of force will escape from the surface of the workpiece at the surface and near-surface defects, forming a leakage magnetic field. The presence of magnetic poles can attract the magnetic powder applied to the surface of the workpiece to form aggregated magnetic marks, thereby indicating the presence of defects. Magnetic particle testing is widely used, mainly to detect defects on the surface or near the surface of magnetic materials. It is often used to detect welds, castings, forgings, etc.
