Analysis of Defect Magnetic Flux Leakage Field Based on Dipole

Abstract:

This paper makes an exhaustive analysis to common defect magnetic leakage field based on dipole theory, obtaining the analytical expression of some common injury shapes and exploiting distribution curves of the magnetic field intensity by MATLAB software, and based on this a new scheme is proposed to simulate various injuries using an ellipsoid tables defect model, and finally confirms the superiority of ellipsoidal model in analysis of defect leakage field by comparison.
