I'd seen this before but it didn't hit me til
rereading it. It relates to the instability of
magnetic fields against each other which is what the
TOMI, Searl, Hamel and other wobble devices try to
take advantage of.
The many times we've all tried to make one magnet
float above another and it always flipped is resolved
in the Levitron by spinning the magnet which prevents
it from flipping.
Well now, turns out you just need a stabilizing
diamagetic field where no spinning is required and you
can make a magnet float between your fingers;

Scientists have now shown that the forces from
everyday materials—wood, plants, even a person's
fingers—can help levitate small magnets placed in a
magnetic field, causing them to hover motionless in
space.
A 157-year-old principle known as Earnshaw's theorem
stipulates that no arrangement of magnets can make
them stay in a stable equilibrium, says Andr‚ K. Geim
of the University of Nijmegen in the Netherlands. The
slightest disturbance would cause one magnet to leap
toward another or fall away.
....certain materials can stabilize a magnet that is
being levitated by another. These so-called
diamagnetic materials have no permanent magnetic
character but generate magnetism that opposes an
applied magnetic field. Superconductors are the
strongest diamagnets, and many ordinary materials are
weakly diamagnetic (SN: 12/6/97, p. 362).
A pair of well-placed fingers—made up of diamagnetic
water, proteins, and organic molecules—is enough to do
the trick. (see photo)
