Краткое описание

We consider natural-convective heat exchange of electrically conducting liquid in a spherical interlayer in the Boussinesq approximation. Free-fall acceleration is directed to the center of the sphere. For the ranges of magnetic interaction S and Reynolds magnetic number Rem 1.5·10−5S ≤ 1.5·10−2 and 1.5·10−8 ≤ Rem ≤ 1 we found the critical number (S/Rem) ~ 450, in passing over which the direction of meridional circulation of liquid undergoes a change in the core of the Earth.
