Why do axisymmetric FEA models of magnets and their fields make the field farther from the axis appear denser than it really is when the flux line mode is enabled? I'm using the F.E.M.M. system at the moment. All integrals and graphs give correct values, but the depicted lines of flux appear distorted density. The planar versions are fine; it's just the axisymmetric versions that appear to have distorted flux depictions.
