Magnetic particle examination for NDT is one of the more economical and speedy ways to ensure ferrous materials are safe and ready for use in the field. In simplified terms, this type of nondestructive inspection is performed by creating a magnetic field around the material being tested and then applying a carrier fluid which holds particles typically made up of iron oxide. Any defect in the surface or just under the surface of the subject material will distort the magnetic field surrounding it, causing the particles in the carrier fluid to be drawn to it. This attraction is easily detected and identified. If there are no flaws in the material, the particles within the magnetic field will remain evenly distributed throughout
