Draw the Earth as a large bar magnet and the magnetic field lines emanating from the Earth. Show the current polarity of the Earth. Is it normal or reverse polarity?
The north magnetic pole provides a direct route to the solar winds that reach the ionosphere and the south magnetic pole is at an angle were the best fitting poles interact.
The magnetic poles have moved from time to time and this is due to the molten alloys of an iron-rich core of the earth. As over the past 150 years, the poles are moving westward at a rate of 0.05° to 0.1° per year from the north or south direction.
As of 2019, the north pole has traveled beyond the Canadian Arctic to 86.448 degrees N 175.346 degrees E. And the south pole is located somewhere 64.28 degrees and 136.59 degrees E, i.e within the Indian ocean in between the Australian Plate and the Antarctic plate.
As per the reversal, there have been 183 reversals over the last 83 million years, due to the lack of data and variety of estimated there has always been a complex process to locate the wandering poles. And these reversals are considered normal for the planet buy for mankind they pose a threat.
