A kit for assisting in the set-up of a fluid pumping or mixing system including a superconducting element capable of reaching a transition temperature during a field cooling process is disclosed. In one embodiment, the kit comprises at least one pumping or mixing element including a levitation magnet and at least one charging magnet substantially corresponding in size, shape, and magnetic field distribution to the levitation magnet. The presence of the charging magnet adjacent the superconducting element during the field cooling process enables stable levitation of the pumping or mixing element, including when in a fluid-filled vessel positioned adjacent the superconducting element.

1. A kit for assisting in the set-up of a fluid pumping or mixing system including a superconducting element capable of reaching a transition temperature during a field cooling process, comprising:at least one pumping or mixing element including a levitation magnet; and at least one charging magnet substantially corresponding in size, shape, and magnetic field distribution to the levitation magnet, whereby the presence of the charging magnet adjacent the superconducting element during the field cooling process enables stable levitation of the pumping or mixing element, including when in a fluid-filled vessel positioned adjacent the superconducting element. 2. The kit according to claim 1, further including a plurality of different charging magnets, each corresponding in size, shape, and magnetic field distribution to the levitation magnet in one of a plurality of different pumping or mixing elements for use in the pumping or mixing system.3. The kit according to claim 1, further including a spacer for spacing the charging magnet from the superconducting element at a predetermined level, whereby the spacing serves to define a levitation height of the pumping or mixing element adjacent the superconducting element.4. The kit according to claim 3, wherein the spacer is fabricated of a non-magnetic material.5. The kit according to claim 4, wherein the spacer is associated with a planar surface of the charging magnet.6. The kit according to claim 1, wherein the pumping or mixing element is an impeller including at least one blade or vane.7. The kit according to claim 1, wherein the charging magnet is annular.8. A kit for assisting in the set-up of a fluid pumping or mixing system including a superconducting element for levitating a pumping or mixing element including a levitation magnet, comprising:at least one charging magnet substantially corresponding in size, shape, and magnetic field distribution to the levitation magnet; and a spacer for spacing the charging magnet from the superconducting element at a predetermined level; whereby the spacer establishes the spacing between the pumping or mixing element and the superconducting element during levitation. 9. The kit according to claim 8, wherein the pumping or mixing element is an impeller including at least one blade or vane.10. The kit according to claim 8, wherein the spacer is associated with one surface of the charging magnet.11. The kit according to claim 8, wherein the spacer is fabricated of a non-magnetic material.12. The kit according to claim 8, further including a plurality of different charging magnets, each corresponding in size, shape, and magnetic field distribution to the levitation magnet in one of a plurality of different pumping or mixing elements.13. The kit according to claim 8, wherein the charging magnet is annular.14. A method of charging a superconducting element for levitating a pumping or mixing element including a first magnet in a vessel, comprising the steps of:placing a second magnet corresponding to the first magnet adjacent to the superconducting element; placing the superconducting element at or below a transition temperature; removing the second magnet; and positioning the vessel including the pumping or mixing element adjacent the superconducting element. 15. The method according to claim 14, further including spacing the second magnet a preselected distance from the superconducting element during cooling, whereby the preselected distance corresponds to a levitation height of the pumping or mixing element.16. The method according to claim 14, further including the steps of:removing the pumping or mixing element from adjacent the superconducting element; raising the superconducting element to above the transition temperature; positioning a third magnet adjacent the superconducting element; placing the superconducting element at or below the transition temperature; and positioning a second pumping or mixing element adjacent the superconducting element. 17. The method of claim 16, further including the step of selecting the second magnet so as to correspond to the first magnet in size, shape, and magnetic field distribution.18. The method of claim 16, further including the step of selecting the second pumping or mixing element including a fourth magnet that corresponds to the third magnet in size, shape, and magnetic field distribution.19. The method according to claim 16, wherein the raising step is accomplished by warming the superconducting element using a heater.20. The method according to claim 14, further including the step of rotating the pumping or mixing element to agitate a fluid in the vessel.
