The Earth's core apparently has more 60 percent more iron on the eastern side than the western side. Could have been happening for the past 500 million years. The core isn't all that old, 500 million to 1,500 million years old. Uneven convection cooling from plate tectonic plate movement could be one cause, though nothing is solidly confirmed about what is causing the unequal crystallization of iron in the solid core. Since we don't know how long this has been happening, it could be since day one, which means any changes would be unnoticeable over time periods we can comprehend. The core is staying round, shaped by gravity. Apparently the magnetism we see on the surface and sky is coming from a molten layer covering the solid core where it could be assumed the iron content is more uniform. It is only after it crystalizes out that the imbalance happens. If we are approaching a tipping point where the switch suddenly pops on, or off, we would notice something. It is possible that the Earth's magnetic field might not continue to be as symmetrical as it seems to be. But this could be taking millions of years to play out. People are now studying how this might effect the Earth's magnetic field. It could be making the field the way it has been all along.
