What is a magnetic particle inspector?

Magnetic Particle Inspectors are professionals who use magnetic particle testing (MT) to detect surface and near-surface flaws in ferromagnetic materials like iron, steel, and nickel alloys. They apply a magnetic field to the part and then apply ferrous particles to the surface; any discontinuities, such as cracks or seams, cause a leakage field that attracts the particles, making flaws visible. This non-destructive testing method is commonly used in industries like aerospace, automotive, and manufacturing to ensure the integrity and safety of metal components.
