  Measurements of magnetic induction near an ice rod in the strong electric
field were carried out. Theoretical estimation of the magnetic induction was
made. It was found that in the average the experimental values of magnetic
induction were an order less than theoretical value. A conclusion about the
non- equivalence of magnetic fields of bound charges current and conduction
current was made. Therefore, the magnetic field near an energized conductor is
caused not directly by moving charges but by their influence on the propagation
medium. The similar effect could occur at diffusion of other particles through
the medium.
