I really wouldn't worry about the magnetic reversal. Here are a couple articles describing how little this reversal will affect us.
The Earth's magnetic field will reverse.
Don't hold you breath. The last field reversal happened nearly 800,000 years ago. Fred Flintstone and our other ancestor cavemen survived. Geological evidence shows that the field has reversed its orientation tens of thousands of times over Earth history. Yet there is no definitive evidence that a magnetic field reversal has ever caused any mass extinction due to increased cosmic ray influx.
The article also describes why a solar flare will not be the cause of the end of the world.
