This NDT method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles (either dry or suspended in liquid). Surface and near-surface flaws produce magnetic poles or distort the magnetic field in such a way that the iron particles are attracted and concentrated. This produces a visible indication of defect on the surface of the material.


  • This course provides detailed theoretical and practical information on all the commonly encountered     magnetic particle testing techniques. Candidates will have the opportunity to use a large variety of      equipment on welds, castings and wrought products.
  • This course is orientated towards candidate NDT inspectors.
