Description
Technical field
The present invention relates to Popular Science Education technical field, particularly relate to a kind of ampere force presentation interaction being applicable to science popularization venue
Device.
Background technology
The power that electrified wire is subject in magnetic field is referred to as Ampere force.It is the important knowledge in senior middle school's electromagnetism, for student
Can understand Ampere force intuitively, occur in that a variety of ampere force presentation device.Such as patent publication No. CN 102298867 A,
CN101520957 A, CN102376186 A, CN 204155523 U, CN 101221707 patent such as A, all for Ampere force
Different demonstration modes be studied, but, their common ground is all suitable for the education category of school instruction；In conjunction with at present
The situation of domestic science and technology venue, due to apparatus structure not system, the feature such as easy care, does not makes the content involved by above patent not
It is suitable for science popularization venue Ampere force is shown.
Summary of the invention
It is an object of the invention to overcome prior art to be not suitable for science popularization venue Ampere force is shown, in order to solve this
Problem, in conjunction with the practical situation of current domestic science and technology center, the present invention devises a kind of ampere force presentation being applicable to science popularization venue
Interactive device, invention device is simple to operate, easy care, can popularize Ampere force knowledge for spectators easily in science popularization venue.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:
A kind of ampere force presentation interactive device being applicable to science popularization venue, including casing and be located at the fixed mount on described casing,
First permanent magnet and the second permanent magnet are that upper and lower coincidence status is arranged on described fixed mount, the N level of the first described permanent magnet
With the S level of the second permanent magnet just to and leave gap, be located at described casing middle position is bearing, and copper dish passes through described first
Gap between N level and the S level of the second permanent magnet of permanent magnet is also arranged on described bearing in movable rotary state；Driving lever
It is outer and be connected with the first wire that one end is located at protective cover, its other end be located on described fixed mount and be provided with contact；Described copper
Being connected with power supply centrally through the second wire of dish；Ammeter is connected with the first described wire and the second wire and is formed back
Road.
Preferably, described copper dish is Flos Chrysanthemi shape.
Compared with prior art, the invention have the benefit that
A kind of ampere force presentation interactive device being applicable to science popularization venue of the present invention, has simple to operate, easy care, is suitable in section
Ampere force knowledge is popularized for spectators easily in general venue.
Accompanying drawing explanation
Fig. 1 is the present invention main TV structure schematic diagram；
Fig. 2 is side-looking structural representation of the present invention.
Detailed description of the invention
Seeing shown in accompanying drawing 1-2, a kind of ampere force presentation interactive device being applicable to science popularization venue, including casing 1 and set
Fixed mount 2 on described casing 1, the first permanent magnet 3 and the second permanent magnet 4 are arranged on described fixed mount in upper and lower coincidence status
On 2, the N level of the first described permanent magnet 3 and the S level of the second permanent magnet 4 just to and leave gap, be located at described casing 1 central authorities
Position is bearing 5, and copper dish 6 is by the gap between N level and the S level of the second permanent magnet 4 of described first permanent magnet 3 and installs
In movable rotary state on described bearing 5；One end of driving lever 7 is located at outside protective cover 8 and is connected with the first wire, its other end
Be located on described fixed mount 2 and be provided with contact 9；Being connected with power supply centrally through the second wire of described copper dish 6；Ammeter 10
It is connected with the first described wire and the second wire and forms loop.The most described copper dish is Flos Chrysanthemi shape.
Demonstration mode and the operation principle of a kind of ampere force presentation interactive device being applicable to science popularization venue of the present invention be: logical
Cross and stir driving lever 7 and make the contact 9 being located at described driving lever 7 other end separate with copper dish 6, described the first wire, the second wire, electricity
Not constituting loop between stream table 10, power supply and driving lever 7 and copper dish 6, now ammeter 10 is without index, owing to no current is by copper dish
6, now the S level of copper dish 6 and the N level of the first permanent magnet 3 and the second permanent magnet 4 does not produce Ampere force, and spectators see that copper dish 6 will not
Rotate；When spectators by driving lever 7 toggle it to get an electric shock 9 with copper dish 6 contact position, now the first wire, the second wire, ammeter
10, constituting loop between power supply and driving lever 7 and copper dish 6, supplies voltages can produce electric current, now ammeter on copper dish 6
10 have electric current instruction, have the copper dish 6 of electric current can be subject in the gap of the N level of the first permanent magnet 3 and the S level of the second permanent magnet 4
Power and rotate, now spectators can observe that the copper dish 6 of Flos Chrysanthemi shape rotates.The phenomenon that the present invention is rotated by copper dish 6,
The Ampere force that electric current is suffered in magnetic field is illustrated to spectators.
The above, be only to presently preferred embodiments of the present invention, be not the restriction that the present invention does other forms,
Any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as equivalent variations
Equivalent embodiments.But, every without departing from the present invention program content, according to the technical spirit of the present invention, above example is done
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
