The dynamics of fibril magnetic fields in a three dimensional chaotic flow shows that two possible final states are realizable: collapse to a singular ring, and expansion to an asymoptotic state with magnetic tension balancing aerodynamic drag everywhere. Flux rings with diameters smaller than the charateristic length scale of the flow are much more likely to collapse than larger rings with the same flux. Scaling arguments predict an asymoptotic field strength given by: $ Bas ~ 3.7 rho ^ {2/3} l ^ {2/3} v_l ^ {4/3} Phi (-1/3) , where\rho is the mass density, l is the charateristic velocity scale, v_l is the velocity amplitude at length scale l, and \Phi$ is the magnetic flux in the fibril. The implications of these results, and other properties of fibril fields for a fibril dynamo model are disscussed. In particular, we consider the combination of fibril dynamics and fibril reconnection in a simplified fibril dynamo. The prospects of full, 3-D multi-fibril simulations with reconnection are examined.
