What is eddy current testing?

Eddy current testing is a non-destructive testing (NDT) method used to detect surface and near-surface flaws in conductive materials. It works by inducing electrical currents (eddy currents) into the material using an electromagnetic probe, and then measuring the response to identify any anomalies, such as cracks or corrosion. This technique is widely used in industries like aerospace, manufacturing, and power generation for inspecting metal components without causing any damage.
