Reply to comment by FootballImpossible38 in What are the forces on Earth’s Inner Core that change its speed? by BayRunner

There is a difference between the inner and outer core. The inner core is approximately solid while the outer core is liquid and is the region that produces the geodynamo. The geomagnetic reversals are more related to the fluid motion in the outer core than the rotation (and/or differential rotation) of the inner core.
