Hi, this time we want to present you very interesting images which we shot while experimenting with a high temperature superconductor and NdFeB magnet spheres. Below you can see a set of astonishing images. What was the experimental setup? We let float two 8mm NdFeB N52 gold plated magnet spheres over a high temperature superconductor made of Yttrium-Barium-Copper-Oxide (YBCO). The superconductor was cooled down to -196°C with liquid nitrogen and is covered with ice and mist. To hold the magnet spheres absolutely upward an additional lifter magnet was used which is not visible in the images.
We observed that a droplet of liquid oxygen, which is paramagnetic, was attracted by the magnet spheres and evaporates abruptly on the surface of the lower sphere. The liquid oxygen accumulated on the surface of the superconductor while experimenting and was not additionally added.
Furthermore we could see nice ice crystal build-ups on the surface of the lower and cooler magnet sphere.
Finally we could also shot nice images of the mist vortexes which built up on the lower side of the magnet sphere. These vortexes consist mainly of water mist and evaporating nitrogen.
This experiment shows a complex combination of superconduction, paramagnetism, diamagnetism, magnetism, thermo-dynamics and fluid dynamics.
We shot these pics with a macro lense because with the bare eye one could hardly see all these effects on the tiny magnet spheres.
