Abstract :
The Letter explains the principles of a new electromagnetic technique, the surface magnetic field measurement technique (SMFM), for the detection and sizing of surface-breaking cracks in metals. The signals associated with circular-arc cracks are examined and techniques for inverting crack signals to crack dimensions, are outlined
