ABSTRACT:
The invention provides a device for creating an excitation field in an apparatus using nuclear magnetic resonance. The structure for creating this field comprises a number of conductors spaced evenly apart at the periphery of a circular cylinder. What characterizes the invention is that, for producing a homogeneous field inside this cylinder, it is sufficient to cause a current to flow through these conductors whose intensity is proportional to the cosine of the angle which locates this conductor with respect to a reference axis system.
