A simple mechanism for the generation of Earth's magnetic field
  Based on the ideal gas model, the dielectric polarization of mantle is achieved, the physical-mathematical model is constructed and the estimate calculation of a dipole of Earth's magnetic field with the considering of rotation, parameters of density and temperature, potential of ionization and static dielectric constant (relative dielectric permittivity), chemical compound of substance in Earth's mantle is executed.
