  Hydrodynamics of plasma in the random magnetic field is considered, which is
characterized by the second moment of magnetic induction. Equations of ideal
magnetic hydrodynamics in such field are received for an adiabatic process. It
is shown that in Euler Equation a new variable is second moment of magnetic
induction enters, for which is received time Equation on the basis of Maxwell
Equations in the magnetohydrodynamic approximation. The one dimension plane
waves in this system are studied and the values of their phase velocities are
received.
