Known reversals of the Earth's magnetic field occur at a rate of five per million years. However, the methods whereby the reversal pattern has been established act as a high frequency cut-off filter and will not record two reversals as separate if they occur close to each other. It is ...
the Earth's magnetic field. These aligned minerals "freeze" into place as the lava cools. Studies of magnetic alignments in basalt flows on either side of the mid-Atlantic ridge provide evidence not only for reversals of the Earth's magnetic field but also for the theory of plate tectonics....
Are pole reversals dangerous for humans? There is no evidence to suggest that pole reversals are directly dangerous for humans. However, the weakening and shifting of the Earth's magnetic field during a reversal could potentially leave us more vulnerable to solar radiation and cosmic rays. This ...

Chris Finlay, senior scientist at DTU Space in Denmark, said, “Swarm data are now enabling us to map detailed changes in Earth's magnetic field, not just at Earth's surface but also down at the edge of its source region in the core. “Unexpectedly, we are finding rapid localised fiel...
