Maxwell equations for spherical sources of the field

© Shuman V.N.

Refined formulation of the system of Maxwell equations for spherical field sources has been given. The distinctive property of electrodynamics of this type sources is presence, along with conductivity currents and currents of displacement, additional sphericity currents as well which existence is caused by the properties of spherical geometry. It is important to note that despite fundamental distinctions between the currents of conductivity, displacement and sphericity of sources they are united by their ability to produce magnetic (including toroidal) field. Just this circumstance is an incentive to introduce a term "current of source sphericity". Inadequate character of classical approach to setting some topical problems of geoelectromagnetism is being stressed as well as the necessity to search new theoretical solutions taking into account more complicated character of electromagnetic response formation.
