Abstract:

From the theory of the radiating magnetic dipole two methods are being derived which permit the location of such a dipole in a dissipative medium rock. One method is based on the trend of field lines, using the angular adjustment of a range-finder antenna for the accurate location even over large distances, the measurement being made by means of earphones. The second measurement uses the intensity distribution of the magnetic field strength yielding in some cases a very simple possibility of evaluation by means of diagrams. The measuring devices and the technique of measurement are explained in detail. A location actually made in a mine is also described in detail, serving as an example of the numerous possibilities of application. Author
