Why does the magnetic field change over time?
- Since the forces that generate our magnetic field are constantly changing, the field itself is also in continual flux, its strength waxing and waning over time. This causes the location of Earth’s magnetic north and south poles to gradually shift, and to even completely flip locations every 300,000 years or so.
And I understand the sun's cycles and intermittent outbursts (CME & something else...?)
I understand that the earth's interior (material composition) promotes at least part of the magnetic nature of earth - ? Does that sound correct?
The metallic / iron elements + maybe the the earths rotating movements - right?
The sun emits various types of radiation - and I think there are 1-2 different solar events that can eject or bathe the earth in bursts of higher levels of magnetic / xray (?) & radio frequency surges -- someone here probably understands that process much better
I have only recently read some basics about the magnetosphere + the polar regions & the electrical nature of the sun
Its freaking fascinating -
What do you guys think about the possibility that those cycles and phenomena experience their own cyclical shifts & changes ?
Also recall seeing a Harvard study that states our earth's rotation - is slowing down
The measurable differences across time dont seem like big #s
But se don't really understand the potential effects of a change to any of those terrestrial/solar elements
Just a wild @$$ thing to contemplate!
Especially if the inner core slows , stops and reverses direction for some insane celestial mechanics type reason
