Magnetic Particle testing is one form of engineering evaluation that detects and interprets flaws in materials, while causing no harm to the materials or structure under examination. It is an exacting science, with highly developed testing techniques.

Magnetic Particle testing consists of inducing a magnetic field into a ferromagnetic material (such as rolled, cast, or forged steel).  The application of magnetic particles and the interpretation of the patterns formed by the particles as they are attracted by magnetic leakage fields (magnetic poles) created at a break in material continuity, such a surface crack.  To ensure visibility, the magnetic particles are coated either with a colored dye easily seen in white light or a fluorescent dye visible under black ultraviolet light.
