You want to look up "Van Allen Belts"
Notice the 11 year cycle they are talking about (the size gets bigger because detection has got better - back in the 1600's there were only small optical telescopes, now we have spacecraft watching everything)? There's also a longer period of fluctuations that looks like beats in sound - that's why you don't remember a blackout 10 years ago: the peak activity was weaker then.
When you know what you want you can start looking for academic sources.
Well, in fact, you know this is the case.I think that there is periodic solar storm that consists of high velocity charged particles.
Again - we know that this is the case. That Windows to the Universe site shows you the proof.Since there is large amount of them which would generate incredible magnetic field moving through. Thus it might vary the earth's magnetic field.

Geomagnetic storms are not a matter of belief, this is not a religion relying on faith, that needs this sort of statement of belief.
If you ever find someone who does not believe in GMS's, they are wrong, and you can prove it within 11 years.
Sorry, I am not expert, I don't know much about geology. I am just applying some basic physics knowledge. Since permanent magnets would change magnetic properties under immense magnetic field due to rearrangement of magnetic domains or magnetic moments, I think that it would be similar in the case of the earth.
Anyway, I extrapolated from elementary physics, there are lots of flaws. If you find any you could correct me.
