movable media

For the purpose of providing a much fuller analysis of electromagnetic processes in electrodynamic devices, it is necessary to carry out the calculation of electromagnetic field in movable and immovable elements of their structure taking into account coordinate systems of moving and stationary items.

While developing the mathematical field mo­dels of electric devices, to simplify the statement of the prob­lem, it is common to apply chain schemes and sub­s­ti­tute equivalent media for the complex structures of a con­struction. Identifying the influence of such sim­p­li­fi­ca­ti­ons on the conformity of the reproduction of elec­tro­mag­ne­tic processes by the models is an important problem, par­ti­cularly when the given methods concern zones that are the sources of an electromagnetic field in the objects.
