This is a drawing of the Earth's magnetosphere. The lobes are highlighted in yellow. Of course the lobes would extend far down the magnetosphere.
The lobes of the magnetosphere are a vast region of the magnetotail between the magnetopause and the central plasma sheet. The lobes have opposite magnetic direction.
