Sure, but you'd be talking about a civilization that could afford to build it, and operate it... a civilization so advanced that they can afford more than double our current energy production just to electromagnetically shield Mars.

And arguably, it's less complicated than beaming energy back to Earth. But still, those could be parallel efforts.
