If there is a defect, the magnetic field distribution disturbance occurs, and the current line will be convergence and deflection at the edge of the defect, as shown in Figure 1.
The quantitative detection of the defect can be achieved through measuring disturbance magnetic field distribution and studying relations with defect sizes [1-3].
In the surface of the tested specimen prefabricates length of 10 mm, width of 0.2 mm, depth of 1 mm crack defect.
