Abstract :
This paper presents a magnetic field analysis of a moving magnetic field type sensor with shading coils developed for eddy current testing. The cracks and defects that are very difficult to detect with the conventional method, can be detected by using this sensor. In this paper, we have carried out the magnetic field analysis with the 2-D and 3-D finite element methods to show the effectiveness of this sensor
