About Earth’s magnetic field
I wrote this to ask respective scientists about Earth’s magnetic field.
It is believed that the magnetic field of the Earth is created by iron-nickel liquid alloy moving around. Scientists have been puzzled about the erratic behaviour of Earth’s magnetic field recently, because its axis has been moving and weakening, and it could be reversed at any moment like it did many times before. They started to think seriously if their model is correct.
I know nothing about this domain but would like to learn more. Because it feels like the theory¹ of James Lovelock about the self-regulating Earth needs to be updated with information about Earth’s magnetic field.
As the model of terrestrial magnetism is under reconsideration presently, I let myself a bit of freedom to see if there would be other plausible models and I’ll be asking questions in different forums about it.
What if, the Earth’s magnetic field was a superposition of magnetic fields coming from inside the Earth AND a field generated by currents on the surface. Telluric currents are a known phenomenon but not well understood. What if the origin of the surface currents is the currents coming from the activity of electricity-generating life forms such as bacteria like geobacter.
It would be the simplest explanation for many phenomena. But scientists look for complex explanations, because it looks like it is taboo to think that life forms can collectively manipulate electric phenomena. It is known that electricity-generating bacteria are everywhere, from the land surface at 300m below to deep realm of the ocean floor. The synchronisation phenomenon is known to happen in groups of many living things of different complexity. Thus, the collective electric actions of bacteria (and maybe fungi) is not impossible thing.
It would explain why and how rainy weather might be triggered by coordinated actions of various life forms, from ungulates to fungi and bacteria. It would explain why a magnetic recursion happened 42k years ago, the potential cause in this case being the possible degradation Earth surface due to the extermination of saiga at the time.
Saiga and other ungulates are carriers of microbiome (hooves and manure). Their population have been varying because of human activity. This might be reflected on the Earth’ magnetic field, which has weakened about 9% over the past 200 years.
Evolution make impossible possible if given enough time.
What would be the serious flaws of this hypothesis?

¹ Let’s avoid to use the name of the theory, because I think it does disservice to the significance and the seriousness of the theory
Update on the letter to James Lovelock.
I sent an email to his sister asking if I can talk to James Lovelock. No answer for the moment.
Today I’ll try to contact one of his former students.
