Introduction to Magnetic Flaw Detector

A magnetic flaw detector is a non - destructive testing (NDT) device used to detect surface and near - surface flaws in ferromagnetic materials. It operates based on the principle of magnetic flux leakage. When a magnetic field is applied to a ferromagnetic material, any discontinuities such as cracks, porosity, or inclusions will cause a distortion in the magnetic field, resulting in a leakage field that can be detected by sensors. This technology is widely used in various industries, including manufacturing, aerospace, automotive, and oil and gas, to ensure the quality and safety of products and structures.
