Fast Calculation Method for the Magnetic Field of Coil above Conductive Plate

Abstract:

A series expansion calculation model was proposed to compute the change of magnetic induction intensity at the coil center above a conductive plate, based on the Maxwell equations, the magnetic vector potential and solution region truncation. When the truncated solution region radius and the summation terms are chosen properly, the computation time can be reduced considerably and preserve the computational accuracy. The model was compared with finite element method and the results agreed very well, and it confirms the suitability of the proposed model and its application prospect in electromagnetic non-destructive testing.
