This method of nondestructive testing, It is based on the physical principle known comomagnetismo, which they exhibit mainly ferrous materials such as steel and consists of the capacity or power of attraction between the metals. Namely, when a metal is magnetic, draws on their ends or magnetic poles or other equally capable magnetized metals.
- Detection of discontinuities in ferromagnetic materials of any kind, on the surface or close to it.
- Método simple
- Rushed up.
