I have heard roomers that you poles are supposed to switch and during the time of the switch out earth would be unprotected from the brutal bombardment of cosmetic radiation.
First we should understand why the earth has a magnetic core. If you look at the different layers of the earth you see a flowing mantel made up of molten metal (iron) and a soled core (also iron). The flowing mantle flows around the core creating a magnetic field.
This is how all electrical generators work except to take advantaged of the electricity created where the earth creates a magnetic field. (This follows the right hand rule if you’re wondering)
The reason the mantle is flowing around the core is because the earth is rotating. so to stop this action the earth has to stop rotating. the only know way to stop something from rotating is the physically come in to contact with it and apply an opposite force. We would have to get hit with a huge meteor or comet and if that happened we would all be dead anyway and the polar shift would be the least of our concern.

This one made me laugh! If something big hit us a magnetic field gone missing is definitely the least of our concern :)
I heard this one long ago... apparently it's something that has already happened many times, too often for life to progress as far as it has if it died each time. :p
