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.
