I was thinking this morning, about the Earth's Magnetic Field, and how the magnetic poles reverse themselves every 200,000 years or so.

And I wondered, what happens the next time the poles reverse? The magnetic field is overdue, according to the above linked article, so it really could happen at any time... but what happens to our technology if the earth's magnetic field reverses itself?

It's a crazy question for a Tuesday morning, I know... but something that struck me as something I'd never thought about before.
