The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals arenât magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
Magnetic particle examination is a highly popular, cost-effective method that is used to facilitate non-destructive examination (NDE) involving ferromagnetic objects. A ferromagnetic material is any material that is capable of magnetization or those highly attracted by magnetic fields. This method is used to detect surface as well as subsurface ferromagnetic discontinuities existing in materials like: Magnetic particle examination is also known as magnetic particle inspection (MPI).
