Claim 0:
1. A magnetic separating conveyor output roll comprising:
(a) a plurality of radial polarity magnetic rings, each magnetic ring among the plurality of radial polarity magnetic rings having a radially outer north pole having axial and oppositely axial ends;
(b) a plurality of oppositely radial polarity magnetic rings, each magnetic ring among the plurality of oppositely radial polarity magnetic rings having a radially outer south pole having axial and oppositely axial ends, wherein the radial polarity and oppositely radial polarity magnetic rings are stacked in an alternating series along a rotation axis; and
(c) a plurality of magnetic strength preserving spacers, each spacer among the plurality of magnetic strength preserving spacers having a radially outer face having axial and oppositely axial ends, wherein the axial end of said each spacer's radially outer face abuts the oppositely axial end of the radially outer north pole of one of the radial polarity magnetic rings, wherein the oppositely axial end of said each spacer's radially outer face abuts the axial end of the radially outer south pole of one of the oppositely radial polarity magnetic rings, said each spacer being non-magnetic at such abutting positions, wherein each magnetic ring's radial cross section is rectangular, and wherein each magnetic ring is segmented by a circumferential array of radially extending seams, and further comprising a first plurality of adhesive bonds, each such bond residing at one of said seams, wherein each seam among the circumferential array of radially extending seams extends from a radially inner end of one of the magnetic rings to said one of the magnetic ring's radially outer end.
