what is a pole reversal

In our solar system has magnetic pole reversal
Every 22 years.

The sun's pole reversal is tied to the sunspot cycle.
Roughly 750,000 years ago.
The sun's pole reversal is tied to the sunspot cycle.
Yes, in the history of Earth, it has happened a handful of times. When it switches we experience what we call a pole reversal. Right now Earth is currently in the process of a pole reversal (the South Pole is moving northwards).
The evidence for Earth's magnetic pole reversals comes from the Geological record. If you look at the fossil polarity of a section of sea floor taken across and to either side of a mid oceanic ridge, there is a mirror pattern of stripes where the rocks have reversed polar directions. Similarly the poles of the Sun reverse every 11 years as the sun goes through a maxima and minima.
the north pole (or south poled during periods of magnetic reversal) has remained fixed and the continents have moved in relation to the pole. Page 90 Chapter Three
magnetic field flips its polarity, so that the magnetic north and south poles switch places. This process is natural and has happened many times throughout Earth's history. Reverse pole fluctuations have occurred roughly every 200,000 to 300,000 years.
The phenomenon you're referring to is known as geomagnetic reversal or magnetic pole reversal. This occurs when the Earth's magnetic field flips its polarity, causing the magnetic north and south poles to switch positions.
