Geomagnetic reversal

A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged.

The Earth's magnetic north pole is drifting from northern Canada towards Siberia with a presently accelerating rate.

It is also unknown if this drift will continue to accelerate.

Present society with its reliance of electricity and electromagnetic effects (e.g. radio, satellite communications) may be vulnerable to technological diruptions in the event of a full field reversal.
