The design of wave transmission with a flexible cylindrical element made of magnetic material is proposed. This material is a textile base filled with microcomposites based on a mixture of divalent and trivalent iron. Micropowder is synthesized in the process of chemical reaction of iron sulfate and iron chloride in the presence of ammonia hydrate. The material with the addition of micromixture acquires magnetic properties. The force with which the material is attracted to the magnet is proportional to the magnetic flux density. A flexible shell with a toothed crown is formed using an epoxy composition. The resulting shell acquires magnetic and elastic properties. A rotating magnetic field placed inside the shell is able to deform it according to the required law. Differential equations of the semi-momentless theory were used to determine the deformation profile of the flexible shell under the action of surface loads. The load function decomposed into a trigonometric series determines the real deflections of the shell. At the same time, the geometry of electromagnetic devices can provide the necessary profile of deformations to create the best conditions for the coupling of wave transmission teeth without the participation of a rigid generator of elastic waves.
