The theorem that no ground magnetic effect is produced by the combination of the vertical current and the associated ionospheric irrotational current holds in the ULF range which is prescribed by wave-period of T≳1s and horizontal wave-length of λ≲10000km when the ionosphere is uniform. The magnetic field observed on the ground is that with no vertical current and it consists of the part produced by the magnetospheric current closing two-dimensionally in the horizontal plane and that produced by the ionospheric source-free current except for that due to the induction current within the earth. It has been found that for longer wave-periods (T≳100s) the contribution of the magnetic field produced by the magnetospheric current to the ground magnetic field is not so much important in the auroral zone except for the case of the wave-length in the east-west direction less than that in the north-south direction.
