Magnetic Particle Training

Magnetic Particle Inspection is a relatively portable NDT method and is used to identify surface and near-surface discontinuities in ferromagnetic materials such as steel and iron. The technique uses the principle that magnetic lines of force (flux) will be distorted by the presence of a discontinuity.

Discontinuities (for example, cracks) are located from the flux distortion following the application of fine magnetic particles to the area under test.
