General overview of the device and physical component of a DC electromagnet.

The paper considers issues related to the theoretical study of electromagnetic phenomena in a certain stationary coordinate system in various variations. The use of electromagnetic force, controlled, easy to handle, which is applicable in a wide variety of sites and devices. The main attention is directed to the analysis of a number of phenomena from the simplest electrical moments, and also in a more complex understanding are presented as the forces of the most powerful attraction, expressed as a very topical issue. It is these aspects that are considered in this study. Of course, the image of such a performance is precisely the electromagnetic design, the physics of which is built from the initial ideas about electromagnetism. The developed theoretical framework is also used to analyze a large number of phenomena, each of which requires its own analysis in all parameters. The description of the algorithm created at the moment is given in this paper. [ABSTRACT FROM AUTHOR]
