superconductor interaction ties the two bodies together resulting in a very stable
mechanical coupling with finite equilibrium separation. This peculiar stability cannot be
attained in conventional mixer designs that employ two permanent magnets.
The Cryogenic temperatures (approx. ā200
o
C) required for the superconducting
material are achieved by an internal cryocooler (Sterling cycle refrigerator).
