Abstract
Hydrodynamics of plasma in the accidental magnetic field is considered, which is characterized by the second moment of magnetic induction. Equations of ideal magnetic hydrodynamics in such a field are derived for an adiabatic process. It is shown that in the Eulere equation a new variable with the second moment of magnetic induction is introduced, for which a time equation on the basis of the Maxwell equation in the magnetohydrodynamic approximation is derived. One-dimension plane waves in this system are studied and the values of their phase velocities are obtained. Refs 7.
