The Sun's pole reversals are tied to its magnetic field dynamics, specifically the solar cycle, which lasts about 11 years. During this cycle, the Sun's magnetic field undergoes significant changes, including the reversal of its magnetic poles. This phenomenon is linked to the movement and interaction of plasma within the Sun, driven by its differential rotation and convection processes. These reversals influence solar activity, including sunspots and solar flares, affecting space weather and conditions in the solar system.
Time periods between Earth's magnetic pole reversals are varied. There are geologic periods where multiple reversals have occurred and periods of no activity. In the last 3.6 million years, there have been at least nine reversals, the last occurring 730,000 years ago.
The direction of the Earth's magnetic field has reversed several times during its history. This causes the North magnetic pole to become a South magnetic pole and vice versa. We know this because of the direction of magnetism in the rocks on the ocean floor, which alternates in 'stripes' on either side of the mid-ocean ridges.
If a fishing pole is 62 linear inches long, it means the total length of the pole when measured from end to end along the curve is 62 inches. The exact length of the straight fishing pole would vary depending on the curvature of the pole. However, a fishing pole less than or equal to 62 inches in length can have a linear measurement of 62 inches.

The north pole becomes the south pole and vice versa. Also any rocks cooling in the reversed field will trap the magnetic polarity prevalent at their time of cooling. This means we can can trace the history of past magnetic reversals.
Rocks lock in their magnetism when they cool.
Other than Earth, Mars is also known to have experienced magnetic pole reversals in its history. Evidence from the planet's crust suggests that its magnetic field has reversed multiple times over millions of years, similar to Earth's magnetic field reversals.
The Earth is the only body in our solar system that has experienced magnetic pole reversals in its history. This phenomenon is when the magnetic north and south poles switch positions, and it has occurred several times over the past billion years.
Paleomagnetism refers to the strength and orientation of the earth's magnetic field at some remote past time. Magnetic field reversals are recorded in deep ocean bottom materials which show that at some ancient times the earth's magnetic poles have reversed, north pole becoming south pole and south pole becoming north pole.
