Abstract:
The use of Eddy currents is a well-known non-destructive technique used in the characterization of cracks in conductive non-magnetic materials. In this paper some experimental and finite element modelling tests with a new probe installed in a mouse pointer device connected to a PC are reported. This probe combines good sensitivity performances at low frequencies by using a giant magnetoresistor (GMR) magnetic sensor with an hand-held device capable of transferring easily its position to the PC.
