One at a time, this little pillar is capable of floating spherical and square magnets. These little magnets permanently escape the gravity of our planet without leaving its atmosphere. Hot air balloons, airplanes, electromagnetic lifted globes -these are all impressive devices. What makes mine different is that they require no power - ever. In this little device I have capitalized on the little known force of diamagnetism, and it is truly amazing. *Please note - The magnet will stay levitated but will not spin continuously. To start the spin again, simply blow on it with a straw or move the maglev slightly to start the spin again.*
Use the words kinetic, gravity-defying, magnets, physics - the general vernacular of my beloved geekdom, and this is what you get. “How is it doing that?” “Is it plugged in?” That’s what you’ll hear when you invite guests to your home or office and they set their eyes on this. Get ready for the conversation to shift.
Handcrafted Magnetic Levitation Sculpture •Gift for the uber gadget geek! •Includes one made to order sculpture with magnets •Measures approximately 5" tall and 3/4" square. •Handcrafted from bismuth metal •Magnets for floating Two 3mm cubes Two 4mm cubes Two 4 mm spheres (Extra magnets are available for purchase.)
HERE’S HOW IT WORKS 1. Place the sculpture on a level surface 2. Slip one of the magnets in either the circular or rectangular hole. * Please note that this device levitates a magnet in one hole at a time. 3. Adjust the height of the top magnet with a simple twist 3. Watch gravity being defied for hours…days…years, it’s up to you.
THE SCIENCE BEHIND THE SCULPTURE The little magnet in the sculpture is touching nothing but air in this unique kinetic piece featuring diamagnetic flotation of a 3 mm-cubed magnet. This new, yet simple, technology requires no power of any kind — just a balancing of bismuth crystals and magnetism.
Bismuth happens to be the metal with the greatest amount of diamagnetism. That means it repels north and south poles of magnets equally. It's a very weak push, and we didn't know about it for a long time. The top magnet attracts the small magnet with enough force to lighten it. Just a little bit. The diamagnetic force of the bottom bismuth crystal can then push the little cube off its surface without pushing it too high into the upper magnet's attractive field. That way it achieves balance in a repulsive pocket of stability between a pair of larger attractive fields, magnetism and gravity.
