Background

Eddy current testing is a method in which an eddy current testing probe is brought into close contact with a conductive test object and scanned, an eddy current is generated in the test object by an alternating current magnetic field generated by a coil of the probe, and the presence or absence of damage of the test object is evaluated based on a change in impedance of the coil due to eddy current disturbance caused by damage. Eddy current testing has led to a number of NDTs (one of the 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 the conductor, the magnetic field will generate a magnetic field in the conductor and in the space surrounding the conductor. Eddy currents are induced currents that flow in a loop, and are called eddy currents because they are in the same form that 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.
