Analysis of a Nondestructive Evaluation Technique for Defect Characterization in Magnetic Materials Using Local Magnetic Measurements

Figure 9

Numerical evaluation of the direct problem for a sample consisting of 5 strips. The computed magnetic induction on the surface of the stack is plotted as a function of the position. (a) Case of nonoverlapping gaps. There is a significant difference in the values of the magnetic induction on the surface at the position of the two gaps. (b) Partial overlap between the two gaps. The position of the two gaps is now more implicitly contained in the magnetic induction at the surface.
