Abstract :
The influence of ground stratification upon the near field of a loop is studied. The results are: a) inclined stratification causes a change of shape of azimuthal dependencies of the magnetic loop field; b) the coupling coefficient of two loops became a function of azimuthal angle; c) by using azimuthal dependence of the coupling coefficient it is possible to retrieve some characteristics of ground layers; d) a method enabling one to locate the horizontal space inclusion is offered
