Yes, geologic times, so like 100 million years or more, not relevant to human life timescales. But even Venus has substantial atmosphere still, including substantial amounts of hydrogen still (with enhanced deuterium concentration due to the atmospheric loss… which could actually be worth mining for nuclear power export).

Making a magnetic field on those timescales is easy, tho, compared to the other challenges. If you cool Venus down, you can place superconducting wires around the equator to generate a magnetic field. This is much easier than the terraforming you had to do.

Would it be possible to have the wires floating in space, instead of placed down on the surface?

So parallel inward orbiting solar sails?
