Aim of the course -

Last update: T_KG (07.04.2008)

The purpose of this basic geophysical course is to introduce to the students the properties of magnetic and electric fields of the Earth, Sun, and other celestial bodies, the problematic of measurements, mathematical-physical description and modelling of these fields and their relations to the physical, chemical, and mineralogical structure of the Earth and its surrounding and to the dynamical processes in the Earth. Part 2 of 2.
