Is Earth’s polarity about to flip? Before we can answer this question we must first have a basic idea of what the ‘geo’-magnetic field looks like. How is it produced, and how it is changing in time? This webinar provides an in-depth exploration of Earth's magnetic poles and their history of flipping every few hundred thousand years.

This webinar is presented by NASA HEAT and delivered by Dr. Sten Odenwald. Below you will find both the original PowerPoint slide deck assembled by Dr. Odenwald and a PDF version of those slides.
