"Venus has a Magnetosphere that is very weak but Venus is extremely hot so it should have an active Geodynamo and a strong Magnetic Field."
No huge molten iron core, no geodynamo. Isn't that simple?
Earths' iron core is the size of Mars. The iron core is so bloody huge that gravity increases as you bore toward the center of the Earth, 1/r2You have free public libraries, free access to university libraries, Google... and you are too goddamned lazy to look something up for yourself. As ye sow, so shall ye reap.
