Lunar gravity is the source of tides. The moon has no substantial mag field. The Earth relies on its mag field to protect us from solar radiation. I dont know about venus but I suspect it does have one, or, like mars (which doesnt have one of any significance), its atmosphere would be stripped away.

The mag field is actually a result of, not an effect on, the interior molten core. It is the movement of the liquid ferrous magma that creates the field.

That was fun to say :)

Sorry. I should've preferenced that with my theory on gravity based on magnetism on molecules. It's my own theory it's not accepted.

Nonsense. Tides are caused by cow flatulence. That's why the Green New Deal folks want to get rid of cows. No tides and the rising ocean levels won't inflict as much damage on low-lying Pacific islands.
