What magnetic field Venus has is induced by its ionosphere and the solar wind, and not by geologic processes. And it is very, very weak. Take your very first long paragraph of this thread, and explain Venus' weather, orbit, and everything else you claim needs a magnetic field to exist, if Venus has basically no magnetic field to speak of. And try reading the links, slowly this time. Seriously. At least make some arguments that stand up. You're not even trying.
