Abstract

The small-scale kinematic dynamo in a two-dimensional chaotic flow is studied. The analytic approach is developed in framework of the Kraichnan-Kazantsev model. It is shown that the growth of magnetic field B\bm{B} fluctuations stops at large times in accordance with so-called anti-dynamo theorems. The value of B2\bm{B}^2 increased therewith in square of the magnetic Prandtl number times. The spatial structure of the correlation tensor of the magnetic field is found.
