Life on Earth is protected by Earth's magnetic field, which deflects high energy charged particles that arrive from the sun and from outside the solar system. This prevents damage to organisms.
For a habitat in orbit around the sun, how much energy would be required to generate a magnetic field providing sufficient protection for the inhabitants (humans, animals, plants) from direct damage from charged particles?
Would it be possible to power this magnetic field using only solar power? That is, can sufficient solar power be gathered by a habitat? I'm interested in the range of sizes of habitat (if any) for which this would be possible.
I understand this is likely to be different for different sized orbits, due to different levels of charged particle bombardment and different amounts of sunlight available. Assume a roughly circular orbit. This can be somewhat closer to or further from the sun than Earth is, or potentially at the same distance as Earth, if one of these options allows for the possibility of a solution.
