Abstract
An open unipolar magnetic structure allowing an arbitrary location of a region of interest which will contain a uniform magnetic field within a cavity. In a preferred embodiment, a yoked magnetic structure is modified to reduce the field perturbations in the region of interest when the latter is arbitrarily located within the cavity. The modification includes the provision of supplemental permanent magnetic members at the opening, the configuration of the supplemental permanent magnetic members being related to the configuration of some of the permanent magnetic members of the magnetic structure that provides the uniform magnetic field.
