  General thermodynamical arguments are used to relate the Hall current to the
part of the magnetic moment originated in "macroscopic current loops". The Hall
resistance is found to depend only on the electron properties in the vicinity
of the Fermi energy, which is the essential advantage of the presented
treatment. The obtained relation is analyzed by using Landauer-Buttiker-like
view to the electron transport. As one of the possible application the Hall
resistance of the periodically modulated two-dimensional electron system in
strong magnetic fields is briefly discussed.
