[Possibility of hydromagnetic wave excitation in a physiologic aqueous solution]

Oscillation processes of Cl- and Na+ ions (the latter form aquacomplexes with 6 water molecules) existing in a constant geomagnetic field are analysed in NaCl aqueous solution. Joint solution of hydro- and electrodynamic equations gives several wave types. Hydromagnetic waves of two modes show the frequency dispersion of phase velocities. This results in the existence of two maxima of oscillation velicity in the frequencies 2-6 Hz and 20-30 Hz close to the cyclotron frequencies of ions. The hydromagnetic waves can have a large amplitude only when there is a variable disturbing force, e.g. a variable component of the magnetic field at the background of the constant field.
