How and why does the sun's magnetic field flip?
Flipping of the sun's magnetic field occurs every 11 years or may be longer. Here is the reason why it does:-
The sun is a huge magnet. Thus is also has Polarity. This Polarity of the sun changes in every 11 years.
In every 11 years there occurs at the height of each of the solar cycle when the sun organises its inner magnetic fields again to release vast or tremendous amount of energy.
This results in the weakening of the sun's polar magnetic fields which is why he reason The Sun's magnetic field flips.
