Magnetic particle inspection - Wikipedia

Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization.

How to Tell If an Element Is Paramagnetic or Diamagnetic

The strength of paramagnetism is proportional to the strength of the applied magnetic field. Paramagnetism occurs because electron orbits form current loops that produce a magnetic field and contribute a magnetic moment. In paramagnetic materials, the magnetic moments of the electrons don't completely cancel each other out.
