Summary

The Pioneer Venus Orbiter has shown that the ionosphere of Venus is often filled with filamentary magnetic fields. These magnetic flux tubes apparently are created at the ionopause in the subsolar region and sink to low altitudes. As they sink they twist and compress, maintaining about the same magnetic flux, 2 to 3 Webers, until they sink below 175 km. Ropes also appear to become kink unstable at about 200 km generating spatial helices. These 3-dimensional structures can lead to increased interaction between flux ropes.
