eddy current inspection

A non-destructive testing (NDT)Refers to a range of techniques and methods used to assess the integrity, quality, and properties of materials, components, or structures without causing damage… method used to detectTo sense or obtain a measurable indication from a feature. surface and near-surface defects or irregularities in conductive materials. It relies on the principle of electromagnetic induction, where a changing magnetic field induces electrical currents (eddy currents) in the material being tested. These eddy currents interact with the material's electrical conductivity and magnetic permeability, allowing the detection of anomalies.
