When the magnetic poles of the earth get reversed, does the earth keep on revolving in the same direction or does it start revolving in the opposite direction?
The Earth will keep revolving in the same direction during a geomagnetic reversal.
There have been a few articles about this phenomenon published during 2018:
I had sought an answer from Dr. Christopher S. Baird and am forwarding his answer. That is incorrect. At present, the north geographic pole points toward the North Star, and the south magnetic pole points approximately toward the North Star. After the next reversal, the south magnetic pole will point away from Antarctica.
When the magnetic poles flip, it will have zero effect on the physical orientation of the earth or the location of its geographic poles. The north geographic pole will still be in the arctic near Canada and point towards the North Star, and the south geographic pole will still be in Antarctica. The rotation of the earth (which determines the geographic poles) has a slight, indirect, complicated influence on the spiraling flow of earth's liquid outer core (which determines the magnetic poles). That is why the geographic poles and magnetic poles are close to being aligned. However, the spiraling flow of earth's liquid core has no effect on earth's overall rotation. This means that changes to the earth's magnetic field do not affect the earth's overall rotation. The sun will still rise in the East.
