The magnetogasdynamic equations are considered with allowance for heat transfer and with account of a possible small fluctuation of the volume force. It is assumed that both the Reynolds number \(Re\) and the magnetic Reynolds number \(Re_m\) are large, and \(Re \sim Re_m\). The solution of the corresponding boundary value problem is found by using the asymptotic expansion in powers of \(1 / Re_m\). The obtained results can be useful in the fast magnetic dynamo theory.
