“…This can be verified by comparing the calculation results of the 3-D EMCN for the Lorentz force with those of 3-D FEA under the same load conditions. Grain-oriented steel is commonly used to enhance transformer performance [14], [15]. Thus, the relative permeabilities in each direction (i.e., the x, y, and z directions) are different.…”
