Abstract
The utility model discloses a magnetic liquid rod climbing device, which relates to a magnetic liquid performance demonstrating device, comprising a container (1), magnetic liquid (2), a glass tube (3), a permanent magnet (4), a support bracket (5), and a cover (6). The glass tube (3) vertically passes through the center of the container (1) filled with the magnetic liquid (2), and the container (1) and the glass tube (3) are adhered by the glue to form a whole body. The permanent magnet (4) and the support bracket (5) are fixed together, and can move in the glass tube (3) along the vertical direction. Through the up-and-down movement of the permanent magnet (4), the magnetic liquid (2) in the glass container (1) is attracted to move up and down along the periphery of the outer wall of the central glass. The device can vividly demonstrate the superparamagnetism of the functional material of the magnetic liquid, and the demonstrating effect is very obvious. The structure is simple, and the operation is also very simple. The utility model can enlighten people to exploit the unknown field of high technology.
Description
Technical field
The utility model belongs to magnetic liquid performance exhibiting device, and the showpiece that is specially adapted to places such as science and technology center, universities and colleges, middle and primary schools is showed.
Background technology
Science and technology center has magnetic liquid performance exhibiting device now at present, has only magnetic liquid climbing device, the problem that this device exists: the strongest in the glass tube apart from the nearest local magnetic field of outer magnetic source, magnetic liquid can only be attracted to the strongest place, magnetic field in the glass tube, magnetic liquid only moves along the glass tube bottom, the climbing phenomenon is not obvious, has influenced the bandwagon effect of showpiece.And the glass tube bottom end cover adopts seal with elastometic washer, the problem that exists magnetic liquid to leak.
Summary of the invention
Technical problem to be solved in the utility model: in the existing magnetic liquid performance exhibiting device, magnetic liquid only moves along the glass tube bottom, the problem that the climbing phenomenon is not obvious and glass tube bottom end cover magnetic liquid leaks.
The technical solution of the utility model:
The magnetic liquid pole climbing device comprises: container, magnetic liquid, permanent magnet, lid.Its glass tube vertically passes the container center of containing magnetic liquid, and container and glass tube stick with glue to connect and be one.Permanent magnet is fixed on the support, places in the glass tube.
By permanent magnet moving up and down in glass tube, attract a part of magnetic liquid in the container to move up and down along the glass tube outer wall.
The beneficial effects of the utility model are, this device can be demonstrated the superparamagnetism of this functional material of magnetic liquid visually, and the demonstration effect is very obvious, simple in structure, operate also very simply, can inspire people to explore high-tech tera incognita.
Description of drawings
Fig. 1 magnetic liquid pole climbing device structural drawing
Among the figure: container 1, magnetic liquid 2, glass tube 3, permanent magnet 4, support 5, lid 6.
Embodiment
With the accompanying drawing is that the utility model is described in further detail for embodiment:
The magnetic liquid pole climbing device comprises: container 1, magnetic liquid 2, permanent magnet 4, lid 6.Its glass tube 3 vertically passes the center of the container 1 of containing magnetic liquid 2, and container 1 and glass tube 3 usefulness AB are gluing to be connect as a wholely, avoids the leakage of magnetic liquid.Permanent magnet 4 is fixed on the support 5, places in the glass tube 3, can move up and down.
The shape of container 1 and glass tube 3 can be rectangle or cylindrical shape.
Permanent magnet 4 and support 5 move up and down in glass tube 3.Permanent magnet 4 attracts a part of magnetic liquid 2 in the container 1 under the action of a magnetic field, separate with remaining magnetic liquid 2 in the container 1, moves up and down around glass tube 3 outer walls, so simple in structure.And permanent magnet 4 is positioned at the center of glass tube, to around the magnetic field that produces have axial symmetry, so can around attract magnetic liquid 2 to move up and down along glass tube, it is fine to demonstrate effect.
The Rb-Fe-B material of the material selection function admirable of permanent magnet 4, because the magnetic field intensity height that rubidium iron boron produces, the magnetic liquid rod climbing phenomenon is obvious more.
The shape of permanent magnet 4 can be a piece shape or cylindrical.
Covering container 1 with lid 6 is in order to reduce the volatile quantity of magnetic liquid.
For the ease of the motion conditions of observation magnetic liquid, container 1, glass tube 3 and cover 6 material and all select material transparent for use are as organic glass or other glass materials.
Permanent magnet 4 is fixed on the support 5, can adopt any mode to drive support 5 and move in vertical direction, thereby drive permanent magnet 4 motions.Support 5 is made by nonmagnetic substance, as stainless steel, aluminium alloy etc.
Use-case: select 1 kilogram keryl magnetic liquid for use, permanent magnet is selected Rb-Fe-B material (remanent magnetism 1.364T for use, magnetic flux density coercive force 1013kA/m, HCJ 1121kA/m), the diameter of cylindrical magnet iron is 50mm, the overall diameter of circle tube glass container is 250mm, and the diameter of glass tube is 60mm.Container 1, glass tube 3 and cover 5 and all select organic glass for use.Move in vertical direction with the driven by motor permanent magnet.Magnetic liquid climbs up along center glass tube outer wall in the container, and effect is very obvious, and is simple in structure, operates also very simple.
