Abstract
The utility model relates to Popular Science Education technical fields, more particularly to a kind of vortex apparatus for demonstrating, including stage body and the organic glass shield being located on the stage body, guide rod is equipped on the stage body and in organic glass shield, coil group is equipped in the lower end of the guide rod, dead ring and becket are successively arranged above the coil group, the dead ring and metal ring are on the guide rod, a bronze gong is equipped in the upper end of the guide rod, the coil group is connected with power supply, switch, and the switch is located on stage body.A kind of vortex apparatus for demonstrating of the utility model, by being powered to coil group and generating magnetic field, due to electromagnetic induction, vortex can be then formed inside becket, according to Lenz's law, becket then can be moved quickly upwards, and the bronze gong at the top of guide rod is beaten to demonstrate vortex phenomenon to spectators.
Description
Technical field
The present invention relates to Popular Science Education technical field more particularly to a kind of vortex apparatus for demonstrating.
Background technique
When magnetic field changes, due to electromagnetic induction, induced current can be generated in the closed circuit in variation magnetic field, it is real
Induced current can be all generated in any conductor on border near this coil.According to Lenz's law, induced current has such
Direction, i.e., faradic magnetic field always hinder the variation for causing faradic magnetic flux.In science and technology center at this stage, also not
There is the device for demonstrating this physical phenomenon.
Summary of the invention
A kind of vortex apparatus for demonstrating designed it is an object of the invention to overcome the deficiencies in the prior art.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of vortex apparatus for demonstrating, including stage body and the organic glass shield being located on the stage body, in the platform
On body and organic glass shield in be equipped with guide rod, the lower end of the guide rod be equipped with coil group, above the coil group according to
Secondary to be equipped with dead ring and becket, the dead ring and metal ring are equipped with one on the guide rod, in the upper end of the guide rod
A bronze gong, the coil group and power supply and switch are connected in series, and the switch is located on stage body.
Compared with prior art, the invention has the benefit that
A kind of vortex apparatus for demonstrating of the present invention, by the way that magnetic field is powered and generated to coil group, due to electromagnetic induction, then
Vortex can be formed inside becket, according to Lenz's law, becket then can be moved quickly upwards, beat the bronze gong at the top of guide rod
To demonstrate vortex phenomenon to spectators.
Detailed description of the invention
Fig. 1 is apparatus of the present invention schematic view of the front view；
Fig. 2 is apparatus of the present invention overlooking structure diagram.
Specific embodiment
Referring to shown in attached drawing 1-2, a kind of vortex apparatus for demonstrating, including stage body 1 and the organic glass being located on the stage body 1
Shield 2 is equipped with guide rod 3 on the stage body 1 and in organic glass shield 2, be equipped with coil in the lower end of the guide rod 3
Group 4, is successively arranged dead ring 5 and becket 6, the dead ring 5 and 6 sets of becket are led described above the coil group 4
On bar 3, it is equipped with a bronze gong 7 in the upper end of the guide rod 3, the coil group 4 is connected with power supply 8, switch 9, and the switch 9 is set
On stage body 1.
A kind of vortex apparatus for demonstrating of the present invention, spectators are by the starting of switch 9 on stage body 1 and close power supply 8, when starting electricity
When source 8, coil group 4 is powered at this time, just produces changing magnetic field around coil group 4, then can be in metal due to electromagnetic induction
Vortex is formed inside ring 6, according to Lenz's law, becket 6 then can be moved quickly upwards, beat the bronze gong for being located at 3 top of guide rod
7.For dead ring 5: when coil group 4 is powered, forming changing magnetic field, since dead ring 5 is insulator, inside it can not
Vortex is formed, would not be moved, the bronze gong 7 for being located at 3 top of guide rod will not be beaten.The present apparatus passes through sound and visual effect
To demonstrate vortex phenomenon.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
