Abstract
Ohm, Hall, and ambipolar diffusions in the partially ionized plasma are considered. It has been shown that a statement of Pandey and Wardle (2011) that only Ohm diffusion is capable of destroying the magnetic flux is not sufficiently correct. Consequences of obtained results are discussed in the light of the dynamo models in the partially ionized plasma.
