Abstract

The invention relates to devices for emitting magnetic fields for NMR analysis of materials. The device comprises a static magnetic field source (1) substantially embodied in the form of a bar (2) whereby one of the poles thereof is embodied as a concave focussing surface (3) in order to obtain static magnetic field lines focussed in a measuring zone (4); an element (5) for emitting an induced magnetic field towards said zone (4); and a polar element (20) for the concentration of magnetic current mounted in such a way that it cooperates with the bar (1) and the element (5) such that it is positioned between the zone (4) and the element (5) and on a straight line (21) passing via the zone (4) and the centre (22) of the surface (3). The invention can be more particularly but not exclusively used in the oil industry for determining the permeability of petroliferous rock, for example.
