Plasmas in eyewalls of sunspots are in pinch state
Pinch configuration is different. Plasma in sunspots belongs into coldest places on the Sun, which refuses your theory effectively.
In above posts, I have already pointed out that the eyewalls of sunspots have huge amounts of the circular electric currents (1,000,000,000,000 Amperes for middle size circular sunspots), so plasmas in eyewalls of sunspots will pinch and be in pinch state, that is, in high temperature (above ten million Kelvin) high density (high pressure) state, so stable nuclear fusion reactions can happen in eyewalls of sunspots.
