So not something that will have an even remote impact on a human timescale.
I wonder how long the transit from 45N to 45S latitudes will be. My gut says the pole will move fastest at the equator (a la the zero crossing of a sine wave).
In the not too distant future humanity will see the magnetic pole at the equator. Wow.
