Thanks for the interesting post! The diagram with increments of 5° is beautiful.
According to http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/MagEarth.html, modern science says that the Earth's magnetic field is caused by "a loop current in the Earth's core". The article suggests the Earth's daily rotation has something to do with it, acting as a "dynamo".
According to Maxwell, a magnetic field is created through the existence of an electrical current. Still, we hear these ideas of dynamos creating the magnetic fields of celestial bodies. A much more likely explanation is that electrical currents in the solar system drive the earth's magnetic field. I will write about this in the future.
One hundred and twenty years ago, Kristian Birkeland wrote these words:
According to our manner of looking at the matter, every star in the universe would be the seat and field of activity of electric forces of a strength that no one could imagine.
We have no certain opinion as to how the assumed enormous electric currents with enormous tension are produced, but it is certainly not in accordance with the principles we employ in technics on the earth at the present time. One may well believe, however, that a knowledge in the future of the electrotechnics of the heavens would be of great practical value to our electrical engineers.
It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. We have assumed that each stellar system in evolutions throws off electric corpuscles into space. It does not seem unreasonable therefore to think that the greater part of the material masses in the universe is found, not in the solar systems or nebulæ, but in “empty” space.
Thanks for your reply. I thought the part about Earth's rotation was curious. A magnetic field would require an electric current relative to the observer. What I learned at university is beginning to look more and more shaky... what did I actually learn?
