ABSTRACT:
The disclosure relates to an open magnetic structure for producing an intense, stable magnetic field, which is amplitude and direction-controlled in a region adjacent to said structure, having at least one magnetic source (4) for producing said magnetic field, characterized in that it also comprises at least one pole piece (5, 6) associated with the magnetic source and having a shape designed so as to control the magnetic field produced.
Application to petroleum or oil research in drilled wells and to surface magnetic imaging.
