3. The permanent magnetic array of claim 2 , wherein the central support tube is a threaded rod.
4. The permanent magnetic array of claim 2 , wherein the plurality of permanent magnets are unthreaded.
5. The permanent magnetic array of claim 1 , wherein the plurality of pole pieces are ferromagnetic to allow for concentration and amplification of a total amount of magnetic flux entering and exiting the permanent magnetic array.
6. The permanent magnetic array of claim 1 , wherein a thickness of the plurality of permanent magnets is greater than a thickness of the plurality of pole pieces.
7. The permanent magnetic array of claim 6 , wherein a ratio of the thickness of the plurality of permanent magnets to the thickness of the plurality of pole pieces is between about 2:1 and about 8:1.
8. The permanent magnetic array of claim 1 , wherein the plurality of pole pieces are bonded to neighboring permanent magnets using an epoxy.
9. The permanent magnetic array of claim 1 , wherein the central support tube is formed from a magnetic material.
10. The permanent magnetic array of claim 1 , further comprising a plurality of cladding rings, one formed around each pole piece, formed from a non-magnetic material.
11. A permanent magnetic array, comprising:
a threaded central support tube;
a plurality of permanent magnets arranged along the central support tube, wherein said plurality of permanent magnets are oriented such that like poles of the magnets are disposed adjacently to concentrate a magnetic field in a direction perpendicular to an axis of the central support tube;
a plurality of pole pieces arranged along the central support tube and threaded to match the threaded central support tube, each pole piece in contact with two neighboring permanent magnets and separating said two neighboring permanent magnets; and
a plurality of cladding rings, one formed around each pole piece, formed from a non-magnetic material.
12. The permanent magnetic array of claim 11 , wherein the plurality of pole pieces are ferromagnetic to allow for concentration and amplification of a total amount of magnetic flux entering and exiting the permanent magnetic array.
13. The permanent magnetic array of claim 11 , wherein a thickness of the plurality of permanent magnets is greater than a thickness of the plurality of pole pieces.
14. The permanent magnetic array of claim 13 , wherein a ratio of the thickness of the plurality of permanent magnets to the thickness of the plurality of pole pieces is between about 2:1 and about 8:1.
