Abstract
The aim of this paper is to determine the best choice of magnetic field to use in a nonlinear surface impedance calculation. Due to boundary relations, a normal component exists and must be generally taken into account. But it can be neglected if we use the metallic side magnetic field for the surface impedance evaluation unless steel is too saturated or the incident field is near to the normal direction. This method has been implemented in the three-dimensional software FLUX3D and validated by comparison with a two-dimensional computation
