Abstract:
1. A magnetized structure that induces in a central area of interest a homogeneous magnetic field oriented along a longitudinal axis of the structure, the structure comprising first and second magnetized rings disposed symmetrically relative to a plane that is perpendicular to said longitudinal axis and that contains said central area of interest, and one median annular magnetized structure disposed between the first and second magnetized rings and also disposed symmetrically relative to said plane, the first magnetized ring being magnetized radially relative to the longitudinal axis with divergent magnetization, the second magnetized ring being magnetized radially relative to the longitudinal axis with convergent magnetization, and the median annular magnetized structure being magnetized along the longitudinal axis, the magnetized structure being characterized in that the median annular magnetized structure is divided into at least two slices along the longitudinal axis and the first and second magnetized rings and the various slices of the median magnetized structure are each divided into identical components in the form of regularly distributed sectors and in that all the components of each slice of the median annular magnetized structure are non-contiguous.
