The invention relates to the simulation of homogeneous quasi-stationary magnetic fields used in analog computing technology in the simulation of three-dimensional currents, as well as in electrical engineering, radio engineering and other areas that require the creation of uniform alternating magnetic fields in limited volumes.

The purpose of the invention is to increase the accuracy of modeling homogeneous peto- cove

FIG. 1 shows a functional 15 diagram of the device; in fig. 2 is a diagram of the windings located on the framework bases.

The device contains a frame 1, which is made of electrically conductive 20 diamagnetic material and has the form of a hollow cylinder with a through-cut i along the generatrix, the bases 3 and 4 of the frame are made of dielectric

Cut 2 is necessary for uncoupling 25 between the windings 8-15, the electrically conductive circuits formed by the electrically conductive cylinder wall. At the edges of the cylindrical surface at the bases of the frame, a winding consisting of two single 30 series-connected sections 5 and 6 connected to an AC source 7 is wired, since the casing 1 is impermeable to alternating magnetic flux, then the magnetic flux is human. the cut wall of the frame 1 does not pass. On the bases 3 and 4, the same number of coaxial and equidistantly arranged annular windings 40 8-15 are placed with winding in the form of flat loops, while the turns of the adjacent windings are located tightly to each other, -Winding windings 8-15 of the same size on each base 3 and 4 in pairs (8 and 45 12, 9 and 13, 10 and 14, 11 and 15) are connected in series and the wx outputs are closed to individual trimmers

The variable variables are cut. Wires B 12, 9, and 15 are connected in pairs and are symmetrically the same.

The device works at once.

From the source 7, the sections 5 are fed and, in turn, the measuring sensor sets its axis alternately on its axis parallel to the lindrical frame of the corresponding parallels 16–19, and the EMF values of the inductive sensor of 20 n average radii are obtained. When the magnetic field is far inside the cylinder 1 at a distance of 4, it is approximately equal to
