   The research of a cylinder shaped electric magnet parameters was carried out and it was shown that at the preset magnetic moment the design of an electric magnet as a bunch of core-electromagnets with parallel axis allows to reduce the weight of the coil and to reduce the power consumption of the device by 20 percent. The level of mutual influence of the magnetic fields of the cores of electromagnets was determined during experiments.
   The scheme of the device for control of temperature fields with temperature It is shown that the greatest influence is observed when there is the minimum distance between the cores (provided that their axis are parallel). In this case the total magnetic moment of the composite construction was reduced by 6 percent at most as compared to the algebraic sum of the magnetic moments of all components of the electric magnet.
