Notes:
We fabricated a scanning Hall-sensor microscope with an active area 50 μm×50 μm that can be served as a simple and conventional tool for nondestructive evaluation of magnetic materials. Using this, we succeeded in magnetic detection of small cracks (∼10 mm long and ∼0.1 mm wide) in mild steels with a yield point of 29 kgf/mm2, caused by a plane-bending fatigue test at a stress amplitude of 28 kgf/mm2 and a frequency of 29.2 Hz. © 1999 American Institute of Physics.
