| Abstract: | On the basis of 3-fluid equations for molecular clouds, a weakly ionized plasma, the magnetic induction equation is derived including the impact of turbulent waves on electrons, which are generated by the drift wave instability. The changing of the magnetic field results from ambipolar diffusion as well as magnetic dissipation. Simplifying the equation under some assumptions, its solution is given for a simple case. |
