Abstract
The research is devoted construction analytical, in particular, exact solution of a problem on movement of the electrically conducting ideal rotating liquid modeling wave movements in a liquid kernel of the Earth. Namely, the problem about radiation of waves in rotating incompressible electrically conducting liquid by the flat wall making, since the initial moment, harmonious fluctuations is considered. Such statement of a problem can serve as the first step to research of influence of heterogeneity of the liquid environment on generation and maintenance of a magnetic field of the Earth.
Keywords:
the electrically conducting ideal rotating liquid
wave motions
the magnetic field of the Earth
