Magnetized transition elements are provided between the magnetized elements that define the cavity of the structure. The magnitudes and directions of the fields of these transition elements are arranged so that the external boundary of the transition elements are equipotential surfaces, and the induction in the transition elements is zero. Separate return yokes are provided for the magnetized elements adjacent the transition elements, that do not contact the transition elements.
