SuperMagna Magnetic Particle
The test by Magnetic Particles can be applied dry or wet to ferromagnetic materials. When applied, the magnetic lines of the induced flux in the material deviate from their path when they encounter a surface or subsurface discontinuity, forming a clear indication of a defect. To perform this test, the well-known Yokes - portable machines with manual contacts - or stationary magnetizing equipment for serial or standardized tests are used. The use of optical readers also represents an important development in the automatic interpretation of results.
