    Reverse or flip? Cause the magnetic poles flip pretty regularly on a geological time scale.

      Yup, leading to a time of basically no magnetic field, and thus increased radiation. This does not appear to be that, more that satellite magnetic observation lets us see into the dynamics of mantle movement. They said 5% was moving the opposite way to normal (east instead of west, so reverse, not flip), which is a pretty big chunk of mass.
