Magnetic flux leakage measurement setup for defect detection
Procedia Engineering, 2010 AbstractThis paper describes a potential technique to detect medium size defects in ferromagnetic specimen by using rather inexpensive but highly sensitive sensors based on the giant magneto resistive effect (GMR) [1]. The sensor effect is used very effectively in ultra high density magnetic recording devices and might thus prove effective in the ...
