n. The phenomena exhibited by a class of substances which, when under the influence of magnetism and freely suspended, take a position with the longer axis at right angles to the magnetic lines of force. From the experiments of Faraday it appears to be clearly established that all matter is subject to the magnetic force as universally as it is to the gravitating force, arranging itself into two divisions, the paramagnetic and the diamagnetic. Among the former are iron, nickel, cobalt, palladium, titanium, and a few other substances; and among the latter are bismuth, antimony, cadmium, copper, gold, lead, mercury, silver, tin, zinc, and most solid, liquid, and gaseous substances. When a paramagnetic substance is suspended freely between the poles of a powerful horseshoe magnet, it points in a line from one pole to the other, which Faraday terms the axial line. On the other hand, when a diamagnetic substance is suspended in the same manner, it is repelled alike by both poles, and assumes an equatorial direction, or a direction at right angles to the axial line.n. That branch of magnetism which treats of diamagnetic phenomena and diamagnetic bodies.
In this video you can see two 8mm NdFeB N52 gold plated magnet spheres floating 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.It can be observed that droplets of liquid oxygen, which is paramagnetic, are attracted by the magnet spheres and evaporate 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 you can see 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.
