Abstract

Magnetic field dynamics in weakly ionized plasmas is an important research subject in both astrophysical and laboratory plasmas. There is great interest in understanding the generation of magnetic field and filament structure (current loops) in weakly inonized plasmas (Brandenburg and Zweibel, 1994, Patel and Pudritz, 1994). Recently Suzuki and Sakai (1995) investigated nonlinear dynamics of Alfvén waves in weakly ionized plasmas, and found the formation of current filament structures associated with the Alfvénic perturbation. We show simulation results for the formation of current loops under the external gravity due to rotational motions in weakly ionized plasmas.
