The stability of the new horizontal axis Levitron 3 is compared with that of the vertical axis
device. The rotation frequency ranges are similar because they are determined by the same
precessional micro-trap, for which some theory is given. But the macro-trap of the horizontal axis
system gives it far greater mechanical stability. Field-line studies allow this to be more easily
visualized. The greater stability allows for educational experiments which could only be
contemplated with the old Levitron: driven precession and nutation and motion along the field lines.
These experiments illustrate some very fundamental space dynamics and several other topics. The
enhanced stability may also lead to electro-mechanical applications.
