Main Question or Discussion Point
I was told today by my physics professor that the Earth undergoes magnetic pole reversals, some of the evidence being molten rocks with magnetic properties on earth orientating themselves towards a different north pole which points towards the north pole being different in the past. He said that the current north pole is actually somewhere in Ontario Canada and within the next year will be somewhere in Siberia. While this is happening of course the south pole is moving up. I was told that this can happen without serious consequence as far as we know. Is that true? What would happen if they became completely reversed and north became south and vice versa? Would our magnetic field and protection from the sun be temporarily suspended or anything else?
