In a validation study, the exposure misclassification was analyzed by using field measures as gold-standard that were collected independently from the model used for field strength calculation.

Finally in this paper the theoretical formula is analyzed, and the effects of the particle volume fraction, particle magnetization and the external magnetic field onthe shear stress are studied.

The effects of magnetizing methods on the effective magnetic field strength showing the defects in the holes with short distances in magnetic particle inspection were studied by calculation.
