associated with an electromagnetic field. In the areas of rail chains, nanomaterials and 
nanotechnology used to produce rail lashes with the best performance, where they work in 
the field of small sizes comparable with the correlation radius, as well as the mean free path 
of electrons, photons, coherence length, and dimensions of the conductor magnetic domains, 
a single electromagnetic field makes it possible to evaluate the occurring phenomena. Field 
theory, based on four interactions, makes it possible to determine the existing polarization 
waves. Power and energy characteristics of electromagnetic interactions are described by the 
same equations. The parameters of these interactions are presented in table. 1.

In electromagnetic interactions, the basic laws of electromagnetism are applied: the total 
current law, Maxwell's formula for the strength of electromagnetic interaction, Maxwell's 
equations, Ampere's law, Bio-Savard-Laplace's law and generalized electromagnetic field 
equations, which are determined taking into account all interactions in the form:

The magnetization of rail chains due to the rotation of wheel pairs, as well as the reverse 
current of the traction network, has a negative effect on the operation of ILSD. Permissible 
values of magnetic induction for the normal functioning of the ILSD are shown in Table 2, 
which shows its limits for rail circuits and insulated joints, as well as on the switches of track 
sections with rails inside the track. It can be seen that the permissible maximum value of 
induction at which the rail circuit will function normally is considered В=700mkT, for 
turnouts is 4900mkT, for insulating joints - 700mkT. 
The operation of the ILSD is also influenced by the geometry of the location of the receiving 
coils on the locomotives. The receiving coils must be firmly fixed to the locomotive in order 
to avoid harmful electromotive forces, and the core should be horizontal to the rail. Incorrect 
installation of receiving coils is shown in Figure 5.
