Abstract
A method for calculating the distribution of the electromagnetic field and forces in a conducting cylinder of finite length is described, when it is subject to the influence of a rotating magnetic field (RMF). The RMF must have the only condition  its amplitude, being the function of coordinates r and z, must not depend on angle j. The axes of the cylinder and the inductor should coincide. The problem is solved in three stages, when the distribution of the electromagnetic field is calculated a) at idle operation of the RMF inductor (it is either set or already known); b) insider the conducting cylinder for an noninductive approximation, i. e. when relative frequency and c) at a final value of . The results of every previous stage are used as initial data for the solution of the following stage. Figs 6, refs 8. Magnitnaya Gidrodinamika 34, No. 3, 241262, 1998 [PDF, 0.93 Mb] (in Russian)
