So I was deciding on ways to end my world in a futuristic scenario, and I had an idea. As we all know, Earth has two poles, and these poles are moving constantly (Magnetic Poles are different from actual Poles). The recent average movement is about 10KM a year. In the past the poles have completely reversed, as in, the North Pole became the South Pole.
This is all because of how the molten core of our planet fluctuates and moves. The outer liquid iron core is constantly moving around a solid inner iron core creating a magnetic field that spans thousands of kilometres into space. This magnetic field (Magnetosphere) protects our upper atmosphere and Ozone from being blown away by charged particles that emanate from the sun.
Astronomers hypothesised that the weakening of Mars' magnetosphere is the reason its atmosphere almost entirely blew away.
Whilst our core is cooling (over billions of years) I wondered if it might create multiple poles, which would lower the extent our magnetosphere reaches and create more holes where the magnetosphere springs from, severely crippling our protection against solar winds perhaps to the point where it blows away our atmosphere.
Anyways, what I'm asking is, could there be more than just two poles?
