The alternating magnetic flux leakage testing is used for the detection of cracks on the surface in steel plate. Generally, the permeability and conductivity in steel are non-uniform. As a result, the detection signal of the electromagnetic inspection method may not be uniform. In this paper, an efficient detecting technique of plural cracks using the amplitude and phase angle of flux density of horizontal (x) coil is proposed. The detecting property of plural cracks in non-uniform steel is investigated using 3-D edge-based hexahedral FEM considering the hysteresis and the non-uniformity of permeability and conductivity in steel. The possibility of the detection of plural cracks using the amplitude and phase angle of the horizontal (x) component is illustrated.
