Geomagnetic reversals, given their known larger-than-10,000-years timeframe and their support for much-slower-than-10,000-years seafloor spreading and plate tectonics, present a problem for young earth creationism.Because stripes of the same number of magnetic reversals away from oceanic trenches are uniform in age, it is clear that this is a global event, which can only be explained by something like a geomagnetic reversal.The theory of seafloor spreading is supported by the existence of symmetrical (in age, polarity, and distance from mid-ocean trenches) magnetic stripes in the rock of the ocean floor.While geodynamo theory is not yet perfect, it very accurately describes the Earth's magnetic field and has no real competitors.

Because the strength of the geomagnetic field is currently declining, it has become the center of some woo. In a geomagnetic reversal, the magnetic poles are flipped.Thomas Barnes also advanced the claim that, instead of global geomagnetic reversals, which require a long time and repudiate a YEC model of the Universe, the reversals that we see were actually local geomagnetic variations, which can occur quite quickly and allow room for a YEC universe. This would only occur if all of these locations had experienced the same magnetic field at the same time, which would be incredibly unlikely if magnetic reversals did not occur on a global scale.
