IIRC we had some really good answers from actual scientists about why magnetic field doesn’t do jack about the atmosphere, but idk why they’re not here. I’ll try to find it.

So there is really no benefit after all? Except maybe radiation in a less dense atmosphere like ours?

Found it

I’m not sure how much thinner atmosphere would be required for radiation to be a big issue - I mean it doesn’t just instantly become an issue once it crosses a certain threshold - but I think it’s likely that any breathable mix is going to reduce the radiation to negligible levels.

Well wow. That's a big weight off, I suppose is one way to look at it lol. Possibly still a good idea for Jovian moons being baked by Jupiter's radiation? But then again, any settlement on a Jovian ice moon will be completely enclosed to begin with, as terraforming is an impractical impossibility I assume.

And why would you want to terraform those iceballs anyway? Just dig down and live in the ice shell or the subsurface oceans. Not much difference really.
