Abstract: According to the conductor's skin effect in low frequency electromagnetic field and the characteristic of comparatively small excitement coil in the benchmark model for eddy current testing, a perturbation model is proposed by combining the axisymmetric field and the 3-dimensional field, in which the disturbed field due to crack in the conductor allows being solved.

Key words: eddy current, crack, disturbance
