Magnetic Crack Detection is a non-destructive testing (NDT) method used extensively to discover surface and near-surface discontinuities in ferromagnetic materials. Think of it as a highly sensitive health check for the metallic giants in industries like aerospace, automotive, and manufacturing. By applying a magnetic field to the metal, any crack or flaw will disturb this field, creating a leakage visible with the use of fine iron particles. It’s like sprinkling pepper on soapy water to catch a breach – simple yet highly effective
