Course objectives
The aim of the course is to introduce some important space-times of compact objects with magnetic fields. The attention will be paid to structures of these space-times, their derivations from Einstein-Maxwell equations, to the methods for charged particles motion description and, especially, to off-equatorial orbits. The course will be finished with lectures on modeling of electrically charged perfect fluid toroidal structures.
