Description
Technical Field

Background
Eddy current testing is one of many NDT (non-destructive testing) methods that use the basic theory of "electromagnetism" as the basis for conductor testing. The generation of eddy currents results from a phenomenon known as electromagnetic induction. When an alternating current is applied to a conductor, such as a copper wire, the magnetic field will generate a magnetic field within the conductor and in the space surrounding the conductor. Eddy currents are induced currents that flow in a loop. This is called "vortex" because it is the same form in which a liquid or gas flows in a loop around an obstacle. If a conductor is placed in the changing magnetic field, eddy currents will be generated in that conductor, and eddy currents will also generate their own magnetic field, which expands as the alternating current rises and blanks as the alternating current decreases. Therefore, when the surface or the near surface of the conductor has defects or some properties of the measured metal material are changed, the intensity and the distribution of the eddy current are influenced, so that the change condition of the eddy current can be detected through the eddy current, and the existence of the defects in the conductor and the change of the metal performance can be indirectly known. Therefore, the eddy current principle can be used for solving the problems of flaw detection (crack and defect detection), thickness measurement (material or coating thickness measurement), sorting and the like of the metal materials.
