Derek LaVallie

Magnetic pole reversal occurs every 500,000 years, scientist estimate. ... Magnetic pole reversal is caused by vortices of liquid metal in the core near each of the magnetic poles. ... This leads to a weakening of the magnetic field in Earth, and eventually to a reversal. Scientists estimate that is has been 750,000 years since the last pole reversal.
