Abstract
Disclosed is a device for generating a homogeneous magnetic field component Bz along an axis Oz in a spherical zone of interest of center O and radius r includes at least one first ring of axis Oz in magnetic material with radial magnetization oriented in a first direction and extending around an opening giving access to the zone of interest ZI, a second ring of axis Oz in magnetic material with radial magnetization oriented in the first direction and offset along axis Oz from the first ring and the zone of interest ZI, the inner radius and the outer radius of the second ring respectively being smaller than the inner radius and outer radius of the first ring.
