N2 - The electromagnetic nondestructive evaluation of cracks in ferromagnetic structures was investigated with respect to the changes of eddy current stream and magnetic flux flow. Numerical simulation showed that both the changes result in detectable signals. The amplitude and phase angle of signals comply with different variation patterns in terms of crack orientation, crack location, the frequencies of excitation current, and etc, When a back-side crack is respectively inspected under the configurations of perpendicular to and parallel to the eddy current streams, the phase difference between the signals of the two configurations is a linear function of crack depth and can be used for crack's depth sizing.
