Each day, facilities across the globe turn to nondestructive testing (NDT) to verify the reliability of parts or materials without causing damage. One of the most popular of these methods is magnetic particle inspection (MPI)—a form of NDT that uses magnetism to detect surface and near-surface defects, cracks, seams or stress points in ferromagnetic materials before parts and materials are placed into service.
