I'm not a scientist but I'm fascinated with Mars. Recently I was thinking of the issue of terraforming Mars, that even if we dumped millions of tons of CO2 into the atmosphere we would still have to deal with radiation and losing that atmosphere to space because it has a very weak magnetic field.
What I was thinking was if would be possible to have a bunch of satallites with strong magnets inside orbit the planet to simulate one? Would this actually work or is it too expensive? Or maybe I'm making assumptions about magnets that are wrong.

The biggest false assumption you make of magnets is their strength over distances. The strength of a magnetic field due to a magnetic charge is inversely proportional to the distance from the charge squared (r^-2). Not to mention even if you got strong enough magnetic charges, on these satellites, you could never keep them in orbit. Also, this wouldn't create anything even remotely similar characteristically to the magnetic field that our planet has.
So no your idea is batshit retarded and you don't know anything about magnets.
