Problems solved by technology

[0009] 1) The measured object is easily damaged
[0010] Since the device uses a superconducting block, that is, a YBaCuO block, it is necessary to use the naked eye to observe the distance between the superconducting block and the magnetic block, so it is easy to squeeze between the superconducting block and the magnetic block , the disadvantage of causing damage to the measured object
[0011] 2) Higher cost
[0012] This measurement device needs to precisely adjust the distance between the measured object and the magnetic block, and uses sensors and data collectors at the same time, so the cost is relatively high

Embodiment 1

[0040] Place the heat preservation container flat on the table, put the superconducting ring in the heat preservation container, and add an appropriate amount of liquid nitrogen to the heat preservation container. To ensure safety, try to avoid liquid nitrogen splashing. In the process of liquid nitrogen cooling the superconducting ring and the heat preservation container, violent boiling will occur due to a large amount of heat absorption. When the boiling basically stops, the superconducting ring drops to the same temperature as liquid nitrogen (minus 196°C), that is, it enters the superconducting state. At this point the preparations are ready and the experiment can begin. This way of cooling the superconducting ring in an environment without a magnetic field is called zero-field cooling.

[0041] Use tweezers to clamp the superconducting ring out of the heat preservation container, put it on the guide rail, and adjust the position so that the plane of the superconducting ...

Embodiment 2

[0043] Put the magnetic guide rail upside down, take out the superconducting ring from the heat preservation container with tweezers, and use a ruler with the other hand to make the superconducting ring stick to the surface of the magnetic guide rail. The tweezers and ruler are removed, and the superconducting ring hangs below the magnetic rail. Gently move the superconducting ring with tweezers, and the superconducting ring can be suspended under the magnetic rail for reciprocating motion.

Embodiment 3

[0045] Place the superconducting ring in the insulated container so that it is in close contact with the inner diameter of the insulated container. Place the spacer on the magnetic rail, put the foam insulation container on the spacer, and add liquid nitrogen to cool it. This way of cooling the superconducting ring in a magnetic field environment is called field cooling.

[0046] In the process of liquid nitrogen cooling the superconducting ring and the heat preservation container, violent boiling will occur due to a large amount of heat absorption. When the boiling basically stops, the superconducting ring drops to the same temperature as liquid nitrogen (minus 196°C), that is, it enters the superconducting state. At this point the preparations are ready and the experiment can begin.

[0047] Remove the spacer, at this time the foam insulation container and the superconducting ring are suspended above the magnetic guide rail as a whole, and the insulation container can be r...

Abstract

The invention relates to an experimental instrument capable of demonstrating a superconductive magnetic levitation phenomenon. The experimental instrument capable of demonstrating the superconductive magnetic levitation phenomenon is mainly used for demonstrating the superconductive magnetic levitation phenomenon and mainly comprises a superconductive ring, a magnetic guide rail, a heat-preservation container, a thermal insulation material, a spacing block, tweezers and a set of weights. The superconductive ring is made of a high-temperature superconductive closed coil. When demonstration is conducted, the superconductive ring levitates above the magnetic guide rail, conducts horizontal reciprocating motion under small external force, and can further levitate below the magnetic guide rail in a reversed mode to conduct reciprocating motion. According to the experimental instrument capable of demonstrating the superconductive magnetic levitation phenomenon, the high-temperature superconductive ring, the magnetic guide rail composed of permanent magnetic blocks and the weights are adopted so that a magnetic levitation test can be conducted and magnetic levitation force can be measured through the weights put on the superconductive ring or a superconductive block.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to an experimental instrument capable of demonstrating the phenomenon of superconducting magnetic levitation. Background technique [0002] The phenomenon of superconductivity refers to the phenomenon that the resistance of a certain material becomes zero when it is lower than a certain temperature (called the superconducting transition temperature Tc). [0003] The first superconductor was discovered in 1911. It is called a low-temperature superconductor, and it can only show superconductivity when it is cooled to minus 269°C (4K). Practical applications of such superconductors are limited because reaching such low temperatures is prohibitively expensive. In 1986, the discovery of high temperature superconductivity (HTSC) made a key breakthrough in the field of superconductivity. Because the cooling conditions and cost are extremely low, HTSC has practical application value. Superconduct...
