The earth’s magnetic field has fluctuated and reversed throughout geological history. Recently, the field has been decreasing in strength and may be poised for a reversal. It’s bad timing insofar as it coincides with an impending solar minimum.
- ringshall 9y agoMagnetic field reversals happen on a completely different timescale than solar minima/maxima. Reversals take a long time to happen: ~1 to 10 ky. Quick on a geological timescale, though.
