Magnetizing Mars. Is This How We Could Do it?

As many of you know, mars has no magnetic field and thus has a very thin and toxic atmosphere because of constant solar wind. If we ever hope to inhabit Mars, we HAVE TO magnetize it. I don't know if anyone else has come up with what I'm about to propose, but I didn't steal this idea. Mars has an iron core, so, in theory, you could magnetize the core of mars like a bar magnet. How I think you could do this is by drilling to the core of the planet on both poles. Then you construct colossal electromagnets and expose the core to a powerful magnetic fields, then, you zap the iron core with thousand's of kilowatts of electricity. Doing this, as far as I'm concerned, would magnetize the core of the planet with out heating it up. The resulting magnetic field would also be much stronger than a normal planets field since high temperature isn't involved. Please, tell me what you think.

    Aug 17 2012: Just a thought - even if we did create a magnetic field on Mars today, it would still be hundreds of thousands if not millions of years before an atmosphere on Mars formed. But perhaps we'd be shielded from the solar winds immediately.

    Also, we've never done planetary "sculpting" before. What if creating a magnetic field on Mars totally jacks up something important and unexpected (i.e. killing microbial life that already exists on Mars or unleashes a chemical or substance we don't know/understand yet)?

    I agree with the assertion that we should treat this planet better and respect our own Earth and its perfect magnetic field so that we don't have the necessity to create a magnetic field on Mars.

      Aug 17 2012: Creating an atmosphere for Mars wouldn't take as long as you think. Once the temperature on mars was raised, which would yield water as a result, we could fill the martian lakes with algae and plant UV resistant plant's on it's surface. It would only take around a century or less to form an atmosphere that humans could safely breath. About possible microbes on Mars, In presume they would be preserved in a laboratory on some sort either on mars or earth. It is likely that such microbes consume minerals and carbon dioxide and since that would all still be there, martian microbes would still be safe.
