Magnetic Particle Inspection
Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials. It works by magnetizing the material and applying iron particles, which cluster at magnetic flux leakage areas caused by defects, making them visible under proper lighting. This technique is widely used in industries like aerospace, automotive, and manufacturing for quality control and safety inspections.
Developers should learn MPI when working in fields involving hardware, embedded systems, or industrial applications where material integrity is critical, such as in robotics, automotive software, or aerospace engineering. It's essential for ensuring the reliability of metal components in safety-critical systems, helping prevent failures by identifying cracks, seams, or inclusions early in the development or maintenance phases.
