AbstractIn order to determine the sense of the photospheric transverse magnetic field measured with a magnetograph, it is shown that: (1) If the magnetic lines of force through the photospheric plane are both divergent and convex upward, Krall’s criterionis true for the transverse field B⊥ much more strongly than for the longitudinal field Bz and the inequality in general becomes(2) If the magnetic lines of force are only divergent upward, we have instead the inequalityfor a force-free field.
