Eddy Current Testing is a conventional non-destructive testing technique that uses the principles of electromagnetism, specifically, electromagnetic induction to conduct examinations. ET is completed through the use of a specially designed coil energized by an alternating current to produce a magnetic field. Eddy Current testing takes its name from Eddies, which are formed when a liquid or gas flows in a circular path around obstacles under the right conditions. ID probes, or Bobbin probes or feed-through probes, are then used to detect changes in electrical conductivity, indicating a discontinuity or flaw in the tested asset.
