Statue made of bismuth with levitating magnetic cube

Physics Toys is a website (and Instagram account) of kinetic curiosities. Check out all the cool double pendulums, which exhibit chaotic behavior that put fidget spinners to shame. Here's a neat statuette of an alchemist who have a levitating magnetic cube between his hands.

The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet levitates trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So modern nuclear physics, applied to the element Bismuth, finally accomplished the aspirations of the alchemists.

The creator of the statue, Ernie McElhannon, is selling it for $299 on Etsy.

Here are some other cool things:

120 Sided Die (Disdyakis Triacontahedron):

120 Sided Fair Dice: mathematically this die has the maximum possible number of sides with equal area. Two mathematicians, Robert Fathauer and Henry Segerman, realized that the oddly named regular polyhedron (disdyakis triacontahedron) had the needed geometry to make a 120 sided fair die. Like the familiar 6 sided die, the d120 has the following properties: every side must have equal area and the numbers on parallel sides (top and bottom) must sum to the same number. The inventors admit that they do not have any suggested use for these dice- they made them purely because mathematically it was possible to do so! ➡️ Follow the link in my profile for info on where to get this and many items featured here are on @physicsfun #mathtoy #mathstoy #physics #physicstoy #geometry #mathfun #polyhedron #d120 #dice #probability #disdyakistriacontahedron #dicelab #mathartfun #science #scienceisawesome

Lenz's Law demo:

Feel Flux: a toy utilizing Lenz's Law- a very strong neodymium magnet falls slowly down a copper tube as though passing through a viscous liquid. Moving magnetic fields produce electric currents in a conductor (such as copper). These currents then produce magnetic fields that have the opposite polarity to the initial field. So a falling magnet makes the copper tube briefly into an electromagnet that repels the magnet. ➡️ Follow the link in my profile for info on where to buy this and many other items featured here on @physicsfun #lenzslaw #neodymium #magnets #magneticfield #eddycurrents #induction #electromagnetism #electromagnet #flux #magneticflux #copper #physics #physicstoy #science #scienceisawesome @feelflux
