OK so this question is not well

posed... I'll try again. Obviously

there is some dynamo operating somewhere

in the Sun to change the field on

timescales of 11 yr, globally. This is

most obviously seen in sunspots -

concentrations of fields into low- and

middle latitude regions. But sunspots are far

removed from polar fields.

So perhaps I should ask instead: given

that there are no magnetic monopoles,

what is the physics that changes the

local net flux near the poles? If we

draw spherical surfaces at various radii

above and below the surface, the flux

out of this surface is zero. So what

physical process effectively arranges,

say, the dipolar field component of the

sun? Are these processes above, below or

within the solar photosphere? There are

arguments one might make for all cases,

I believe, but what do data tell us?

Typical of solar physics, this question requires one to be an expert on several different branches of physics at once! And there are so many unknowns, particularly for the interior and for the dynamo. This is indeed a loaded question, and out of my comfort range. But one I often puzzle about.

I did some work couple of years ago (http://adsabs.harvard.edu/abs/2011ApJ...738..189M) on coronal rotation. This got me thinking a lot about how it is possible for the corona to rotate at quite different rates to the photosphere, particularly above the poles. There must be considerable and constant reconnection for this to occur, and if so, it must have some contribution to reconfigure the global field and the 11-year polarity reversal.

The reversal of the solar polar fields are discussed by Svalgaard and Kamide in http://www.leif.org/research/ApJ88587.pdf

you might be interested on my aproach where I document almost everything about sun spots, solar wind etc
