Abstract
The utility model relates to a physical demonstrating apparatus used for demonstrating an electromagnetic effect of superconductive materials, which comprises a cryogenic container, a sample of the superconductive materials, a permanent magnet and a relevant clamping device, wherein the superconducting critical temperature of the sample of the superconductive materials is above the liquid nitrogen temperature. The cryogenic container is an ordinary thermos bottle, and a vacuum interlayer is not silvered or the half side of the vacuum interlayer is silvered or is provided with a transparent window. The utility model has the advantages of simple structure and low demonstrating cost, and can be widely used for junior colleges, normal colleges, secondary schools and popular scientific demonstrations.
Description
The utility model relates to a kind of making of physics demonstration instrument.
Superconductor has diamagnetism, and imperfect type-ii superconductor has the flux pinning effect, along with the appearance of high temperature superconducting materia, finds the diamagnetic and paramagnetic characteristic magnetic levitation of reflection superconductor and the experimental phenomena that magnetcisuspension is hung in 1988.But owing to lack suitable experimental provision, this experimental phenomena is difficult to generally perform.
The purpose of this utility model is to make a kind of ocular demonstration instrument that reflects the empty locking phenomena of superconductor magnetcisuspension.
Technical solution of the present utility model is: this apparatus for demonstrating comprises high temperature superconducting materia, is with the Dewar flask of transparent tube and has magnet and the clamping device of manipulation superconductor.High temperature superconducting materia is with the YBCO(yttrium barium copper oxide of melting structural growth) material, its superconductor critical temperature and has high critical current density and strong flux pinning force more than liquid nitrogen temperature (77K).Low-temperature (low temperature) vessel for the ordinary thermos bottle courage for well, not silver-plated or side half part is silver-plated or leave transparent window in vacuum interlayer, clamping device is two rods, a stick end is fixed with permanent magnet, another rod has the string bag or clip clamping superconductor sample.
At room temperature superconducting sample is put into liquid nitrogen container, the rod of holding magnet and sample are placed sample a little while in liquid nitrogen at a distance of 10 millimeter when putting in, and propose liquid level, can see that superconducting sample is suspended from magnet below certain distance, follows magnet movement.
The utility model device is simple, and cost is low, and the technology of superconductor preparation is simple, and this experiment can generally be applicable to junior college, normal colleges and schools, middle school and science popularization demonstration, as long as liquid nitrogen can be provided.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation.
