1. A magnetic system suitable for use in a rotating machine or a gear box, comprising at least a first array structure containing at least a first plurality of like discrete magnetic segments and extending along a central axis, with each segment in the first plurality:
(i) having an elongate length, relative to its width, extending along a major side thereof in a direction parallel with the central axis,
(ii) including a pole with a like characteristic field distribution including a maximum field strength direction and the same maximum field strength,
(iii) having a surface, with a predefined shape in cross section, from which the maximum field strength direction points outward therefrom, about which surface the segment is axially rotatable prior to fixed placement of the segment in the first array of like magnetic segments circumferentially positioned about the central axis,
(iv) fixedly arranged with its major side extending in a direction parallel to directions along which the major sides of other segments in the first plurality extend, and
(v) positioned to extend in a direction parallel with the central axis to collectively form, in combination with others in the first plurality, the first array of like magnetic segments, which first array is configured as a first ordered sequence having field poles of the magnetic segments rotated with respect to one another as a function of position in the first sequence, this resulting in shifts in angular orientations of the field poles among the magnetic segments in the first sequence.
