Optimization and Validation of Rotating Current Excitation with GMR Array Sensors for Riveted Structures Inspection

In eddy current non-destructive testing of a multi-layered riveted structure, rotating current excitation, generated by orthogonal coils, is advantageous in providing sensitivity to defects of all orientations. However, when used with linear array sensors, the exciting magnetic flux density ( B...
