Abstract
The eddy current problem of recognizing a crack on the edge of a rivet hole is analyzed numerically by using the current vector potential method. The vertical field is induced by the disturbance of the sheet eddy current on a thin plate. The vertical field is evaluated for a visualization technique with magnetooptics. A vague image of a crack is improved by cancellation of signals of the rivet hole in the numerical analysis
