Why is only half of Mars magnetized?

#22Does this indicate that half of mars has useful enough magnetism to shield it from solar radiation for human habitation purposes? (I honestly don't know the answer or how to discern it from google).
NASA wanted to (or still) put a satellite at L1 point near Mars to create an artificial magnetic shield. http://www.popularmechanics.com/space/moon-mars/a25493/magne...

The field is only 2.5% of Earth's. That's way too weak, I suspect.
Isn't Mars around 2AU from the sun? That should weaken solar wind by quite a bit, i.e. by around 4x.

#25At first I thought this said "monetized". Which, I think, is an interesting comment on the state of the world, or at least my perceptions of them.

Only if solar wind can be modeled by a uniform field. Radiation from flares might not drop off in an inverse squared relationship, but I'm not an astrophysicist so this is just speculation.

#27Y'all know how it happens - unclear specs, lousy pay, outsourcing to India

#28I wonder how can half a planet be low-lying without reconsidering the zero of such measurements?
Same thing for high half. Maybe just agree that Mars is located one mile further, high half direction?

center of mass != geometric center

Flares shouldn‘t be uniform, but I‘m doubting that they‘d disturb a terraformed Martian ecosystem much as they are quite rare. I‘m guessing some moderate EM hardening of electronics would be enough. As we should have here btw., the next one-in-200y flare is not going to be pretty.
