Plots of the magnetic field in the winding area (the gap is at (0, bw/2) in each plot). The first two figures plot the magnetic calculated magnetic field using traditional the flux path calculation. The lower two plots use an improved method to calculate the flux path that may reduce error. For an explanation of the method, see A. F. Hoke and C. R. Sullivan, " An Improved Two-Dimensional Numerical Modeling Method for E-Core Transformers ."
