Which of the following methods of inspection is mostly used for ferromagnetic materials? Correct Answer Magnetic particle inspection

Magnetic particle inspection (MPI) is a method of locating surface and subsurface discontinuities in ferromagnetic materials. In this method, the material or part is magnetized and then the magnetic discontinuities occur which indicates the size, shape and extent of discontinuities.
