Making Furniture with Magnetism and Gravity

According to the bio on his website, Jólan van der Wiel admires objects which show experimental discovery and are translated into a functional design. His Gravity Stools demonstrate that perfectly. Using a custom magnetic material and a machine with large magnets to stretch the legs off the seat of the stool, he manufactures a product which is “characterized by the freakish and organic shapes that are so typical of nature itself.”

Superconductor levitates around circular supermagnet track

High-temperature superconductor (Yttrium barium copper oxide) floating in the magnetic field of Neodymium magnets. This phenomenon is called the Meißner-Ochsenfeld-Effect and was discovered in 1933. The superconductor has to be cooled with liquid nitrogen which has a temperature of 77 K or −196 °C. If it is placed in a strong magnetic field it remains in its position. It also works if you turn the track upside down
