`I wrote that example before FEMM has the "depth" parameter included. Before that time, it was assumed that all results were per meter of length in the into-the-page direction. For compatibility, if there is no depth parameter in the file, it assumes that the depth is 1 meter, in whatever the current units are--thus the 39.37 inches. I will fix this particular example so that the depth actually comes up as 1 inch--thanks for pointing this out.`
