Eclipse view of the Sun's magnetic field

Total Eclipse Pic

I'm finally taking a stab at processing my photos from an August trip to Wyoming to view North America's recent total solar eclipse. This pic from during totality is processed to highlight the magnetic field lines at play around the sun. You'll notice there are 3 prominences on the right, giant plasma filaments that follow localized magnetic fields. Do those fields help create the prominences? Do the prominences cause the fields? I don't think we know the answer to that yet.

These magnetic field lines and prominences are constantly changing and form a fingerprint for eclipse events. Many photographers and solar astronomers can tell which event pictures were taken on by examining those fingerprints.
