The electromagnetic element consists of a magnetic circuit

The coil 2 contacts in its depth with a ferromagnetic coil 4, which together with the coil 2 is covered by, coil 5, with -,. / Not otherwise. at least one, second current source 9 of the power supply unit 3. The adjacent turns 7, respectively, of the windings 2 and 5, respectively, are provided with a gap, whereby two pairs of poles 1C and 11 are formed.

In the exemplary embodiment shown in Fig. 3, the eero-magnetic coil 4 is connected by ferromagnetic contacts 15 to the magnetic circuit 1 in sections 17, 16.

In the embodiment shown in Figure 2, the coil 2 and the ferromagnet 4 are coaxially arranged, in particular by being applied to the ferromagnet 4 on a conductive layer 13 corresponding to the coil 2.

In another embodiment shown in FIG. 3 ferromagnetic. helix 4 is enclosed by a coil 2 having a screw-like shape 12.

In another embodiment shown in Figure 4, the ferromagnetic helix 4 is positioned in a helical channel 14 of the magnetic core 1.

In another embodiment not shown in the figure, the magnetic core 1. has a helical shape and is concentrically arranged relative to the ferromagnetic helix 4 and optionally between the turns of the ferromagnetic helix 4. In another embodiment, the windings 2 and 5 are connected to each other. Only one of the windings 2 and 5 is mounted alternatively.

The electromagnetic element acts as follows: When the windings 2 and 5 are engaged in the wound, the wound block 3 forms two pairs of poles 10 and 14, creating two pairs of electromagnetic fields that interact depending on the mutual arrangement of the ' the power lines, the direction and type of current flowing through the windings 2 and 5, etc. The direction of the force lines of the second pair of poles 11 is determined by the direction of the end of the ferromagnetic helix 4, depending on which the force lines of the fields are selected longitudinally, transversely or at a meme angle. The direction of the electromagnetic fields power lines is a function of the current direction in the windings 2 and 5.

The flowing current in the coil 2 creates magnetic fields.

-4c in magnetic circuit 1 and the ferromagnetic coil 4. When one of the AC windings 2, 5 is energized, a current is generated in the other coil, creating a second electromagnetic field.

When connected in two or more regions 16, 17 of the ferromagnetic helix 4 to the magnetic circuit 1, through contacts 15,. closed / mendu sections ^ and / $ / ferromagnetic circuits with transformer properties and open circuits are formed. By connecting magnetic circuit 1 and the ferromagnet 4 in only one section, the ferromagnetic / circulating / open circuits are open.

The differential and integral capabilities of the element are determined by the direction and direction of the force lines of the two fields, by the number and $ 2 position of the contacts between the magnetic circuit 1 and the ferromagnetic coil 4, by the number of coils simultaneously fed and the current flowing through them.

Orientation in one direction of the ferromagnetic helix 4 and the coil 2 increases the interaction between them.
