Magnetic Particle Testing (MT)

Magnetic Particle Testing (MT) is a nondestructive method used to detect surface and near-surface flaws in ferromagnetic materials like iron and steel. The process involves magnetizing the material and applying fine magnetic particles, which can be dry or suspended in a liquid. If there's a crack or defect, the magnetic particles gather around it, creating a visible indication. This allows inspectors to identify defects without damaging the part. MT is widely used in manufacturing, maintenance, and safety inspections to ensure the integrity of critical components and structures.
