Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of ampere force presentation suitable for science popularization venue are interactive
Device.
Background technology
The power that electrified wire is subject in magnetic field referred to as Ampere force.It is the important knowledge in senior middle school's electromagnetism, for student
Can intuitively understand Ampere force, occur in that a variety of ampere force presentation devices.Such as A of patent publication No. CN 102298867,
The patents such as CN101520957 A, CN102376186 A, CN 204155523 U, the A of CN 101221707, all for Ampere force
Different demonstration modes be studied, still, their common ground is all suitable for the education category of school instruction；With reference to current
The situation of domestic science and technology venue, due to apparatus structure not system, not the features such as easy care, makes content involved by above patent not
It is suitable for science popularization venue to be shown Ampere force.
The content of the invention
It is an object of the invention to overcome prior art to be not suitable for science popularization venue to be shown Ampere force, in order to solve this
Problem, with reference to the actual conditions of current domestic science and technology center, the present invention devises a kind of ampere force presentation suitable for science popularization venue
Interactive device, invention device is simple to operate, easy care, easily can popularize Ampere force knowledge for spectators in science popularization venue.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of ampere force presentation interactive device suitable for science popularization venue, including casing and the fixation that is located on the casing
Frame, the first permanent magnet and the second permanent magnet are arranged on the fixed mount in coincidence status up and down, the N of described the first permanent magnet
Level and the S levels of the second permanent magnet just pair and leave gap, and be located at the casing middle position is bearing, and copper dish pass through described the
Gap between the N levels of one permanent magnet and the S levels of the second permanent magnet and on the bearing in movable rotary state；Driving lever
To be located at protective cover outer and be connected with the first wire for one end, its other end and be located on the fixed mount and be provided with contact；It is described
Copper dish are connected centrally through the second wire with power supply；Ammeter is connected and formed back with the first described wire and the second wire
Road.
Compared with prior art, beneficial effects of the present invention are：
A kind of ampere force presentation interactive device suitable for science popularization venue of the invention, with simple to operate, easy care, is adapted to
Easily Ampere force knowledge is popularized in science popularization venue for spectators.
Brief description of the drawings
Fig. 1 is main structure diagram of the present invention；
Fig. 2 is side structure schematic view of the present invention.
Embodiment
Referring to shown in accompanying drawing 1-2, a kind of ampere force presentation interactive device suitable for science popularization venue, including casing 1 and set
Fixed mount 2 on the casing 1, the first permanent magnet 3 and the second permanent magnet 4 are arranged on the fixed mount in coincidence status up and down
On 2, the N levels of described the first permanent magnet 3 and the S levels of the second permanent magnet 4 just pair and leave gap, are located at the casing 1 central
Position is bearing 5, and copper dish 6 pass through the gap between the N levels of first permanent magnet 3 and the S levels of the second permanent magnet 4 and installation
In movable rotary state on the 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
With being located on the fixed mount 2 and provided with contact 9；The copper dish 6 are connected centrally through the second wire with power supply；Ammeter 10
It is connected with described the first wire and the second wire and forms loop.
The demonstration mode and operation principle of a kind of ampere force presentation interactive device suitable for science popularization venue of the invention be：It is logical
Cross and stir driving lever 7 and the contact 9 for being located at the other end of driving lever 7 is separated with copper dish 6, described the first wire, the second wire, electricity
Loop is not constituted between flow table 10, power supply and driving lever 7 and copper dish 6, now ammeter 10 is without index, because no current passes through copper dish
6, now the N levels of the permanent magnet 3 of copper dish 6 and first and the S levels of the second permanent magnet 4 do not produce Ampere force, spectators see that copper dish 6 will not
Rotate；When spectators by driving lever 7 toggle it to electric shock 9 and the contact position of copper dish 6, now the first wire, the second wire, ammeter
10th, loop is constituted between power supply and driving lever 7 and copper dish 6, supplies voltages can produce electric current in copper dish 6, now ammeter
10 have electric current instruction, have the copper dish 6 of electric current the first permanent magnet 3 N levels and the second permanent magnet 4 S levels gap in understand by
Power and rotate, now spectators can observe that copper dish 6 are rotated.The phenomenon that the present invention is rotated by copper dish 6, to spectators' exhibition
Electric current Ampere force suffered in magnetic field is shown.
It is described above, it is only the preferred embodiments of the present invention, is not the limitation that other forms are done to the present invention,
Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But, every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
