In the future it is quite possible that an inflatable structure(s) can generate a magnetic dipole field at a level of perhaps 1 or 2 Tesla (or 10,000 to 20,000 Gauss) as an active shield against the solar wind."
Indeed, “in the future” seems to be doing quite a lot of heavy lifting. As noted, 1-2 Tesla is a pretty powerful magnet - so you’d need a pretty big and powerful magnet.
It also doesn’t completely protect the entire planet just two critical points on the surface.
That is certainly an important catch.
I… don’t think that’s true? The L1 point is fairly close (in solar system scale) to the planet.
