Where are most of the magnetic particles located?
If the material is sound, most of the magnetic flux is concentrated below the material’s surface and the particles follow the induced magnetic field ( Shull, 2002; TWI, 2008).
What is the process of magnetic particle testing?
Magnetic Particle Testing, also known as Magnetic Particle Inspection (MPI) is the process whereby a component is magnetised to produce lines of magnetic flux within the component.
How does a magnetic particle respond to a drive field?
Particles that are in the FFR respond to the drive field, but those which are far away from the FFR and saturated by the bias field do not. The particles in the FFR give a periodic magnetization response which induces a voltage in a receive coil.
How are magnetic particles used in NDI inspection?
Magnetic particle inspection is a simple NDI method used to detect cracks at the surface of ferromagnetic materials such as steels and nickel-based alloys. The inspection process begins with the magnetisation of the component. The surface is then coated with small magnetic particles, which is usually a dry or wet suspension of iron filings.
