Magnetic Particle Inspection - an overview ScienceDirect Topics
WebMagnetic flux leakage (MFL) testing is a widely used nondestructive testing (NDT) method for the inspection of ferromagnetic materials. This review paper presents the basic principles of MFL testing and summarizes the recent advances in MFL. An analytical expression for the leakage magnetic field based on the 3D magnetic dipole model is provided.

WebMagnetic Particle Inspection The depth d if the penetration can be calculated as follows: d = 500 [f.c.u] -1/2 When f = frequency, c = conductivity and u = relative permeability. In most common steels at 50/60Hz the penetration of A.C. induced fields is less than 2mm (0.080”). The skin effect is absent in D.C. magnetising. blew ashore
