The
SUPER LEVITRON is an amazing "Anti-Gravity"
Top. |

Floating on a cushion of magnetic force, held in place by the stabilizing effect of gyroscopic motion, the Levitron levitating top is a toy that proves Arthur C. Clarke's maxim: Sufficiently advanced technology is indistinguishable from magic.
Note that Dr. Post's Inductrack does not require any spinning objects to provide vehicle stability. Instead, an Inductrack vehicle uses a second set of small Hallbach arrayed permanent magnets located sideways which react to sideways mounted ferrite coils to provide the needed lateral stability.
We bought our Super Levitron and Perpetuator at our local "Store of Knowledge". You can search the Internet for "Super Levitron" on any of the search engines and go comparison shopping.
Fair warning: it takes a lot of time and patience to make the top levitate for more than a few seconds at a time--not only do operators have to figure out the precise weight for the top by trial and error, spinning the top exactly on its axis is a painstaking skill to acquire--but the end results are astonishing! Levitron is a challenging educational toy will provide hours of entertainment as you learn to spin the top, and also determine the correct weight that needs to be added for stable levitation.
Perpetuator
Once you have mastered the SUPER LEVITRON you are ready for the next level - perpetual levitation. The PERPETUATOR is a special electromagnetic drive device that, when placed below the SUPER LEVITRON base magnet imparts spin torque to the magnetic top allowing it to remain levitated indefinitely in space. The PERPETUATOR silently and invisibly spins the SUPER LEVITRON top at more than 2.5 million revolutions per day! It need not actually touch the SUPER LEVITRON magnetic base to operate. It can actually be placed below the table top and give the illusion that the top is spinning with no visible means of support.
