Weak, Quiet Magnetic Fields Seen in the Venus Atmosphere. [PDF]
, 2016 The existence of a strong internal magnetic field allows probing of the interior through both long term changes of and short period fluctuations in that magnetic field. Venus, while Earth's twin in many ways, lacks such a strong intrinsic magnetic field,
