The most common method of magnetic particle inspection uses finely divided iron or magnetic iron oxide particles,held in suspension in a suitable liquid (often kerosene).This fluid is referred to as carrier.The particles are often colored and usually coated with fluorescent dyes that are made visible with a hand-held ultraviolet (UV) light.The suspension is sprayed or painted over the magnetized specimen during magnetization with a direct current or with an electromagnet,to localize areas where the magnetic field has protruded from the surface.The magnetic particles are attracted by the surface field in the area of the defect and hold on to the edges of the defect to reveal it as a build up of particles.
