THEORETICAL INTERPRETATION OF COSMIC MAGNETIC-FIELDS

The paper discusses the possibility of interpreting the magnetic field s of astronomical bodies in the framework of a unified field theory. U sing one of the solutions of the generalized field theory, a direct re lation between the polar magnetic field, the angular velocity and the gravitational potential of the body considered, is obtained. The geome tric model used for applications has spherical symmetry and is of the type (FIGI). The predictions of the theoretical formula, obtained from the model, are compared with available observational data, and with t he empirical formula of Blackett. The theoretical formula gives a poss ible interpretation of a seed magnetic field which will develop and pr oduce the large-scale magnetic field observed for celestial objects. T he formula shows that the field is generated as a result of rotation o f a massive object.
