SUMMARY:The dynamics of magnetic flux tubes and a new theory related to th
 e origin of the solar hemispheric helicity rules (Contributed talk) - Nich

DESCRIPTION:The concept of magnetic "flux tubes" as isolated cylindrical m
 agnetic entities has been instrumental in our intuition pertaining to the 
 origins of solar magnetic observations.&nbsp\; However\, magnetic fields a
 re generally space-filling and the so-called "flux tubes" are really conce
 ntrations of field and are not isolated entities in a field-free backgroun
 d.&nbsp\; We examine the effects of this difference\, and\, in particular\
 , find a simple new effect that can explain (or perhaps contribute to the 
 explanation of) many aspects of the recent observations of solar helicity.
