Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of interactive device of demonstrating current magnetic effect.
Background technology
The magnetic field of electric current be it is a kind of can not touch but the particular matter form of objective reality, only with the displaying of visual pattern
The objective reality of current field can just enable people to understand this phenomenon of the magnetic effect of electric current.In traditional teaching, to drill
Show the magnetic effect of electric current, often using coil, switch are connected with power supply, coil is placed around small magnetic needle, observed after energization
The experiment of the change of small magnetic needle carries out teaching demonstration.But there is phenomenon not obvious, trivial operations, demonstration dress in this demonstration mode
The problem of putting complexity.
The content of the invention
It is an object of the invention to a kind of structure letter for overcoming the shortcomings of demonstration mode and device in the prior art and providing
It is single novel, it is capable of the interactive device of the magnetic effect phenomenon for showing electric current of visual pattern.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of interactive device of demonstrating current magnetic effect, including stage body and the caging bolt that is located on the stage body, installed in institute
It is coil block to state on caging bolt, and described coil block is connected to power supply by pressure regulator, in described coil block
Outside is provided with protective cover, and transparent bowl is provided between described coil block, and multiple clips are provided with described transparent bowl.
Preferably, described transparent bowl is transparent acrylic glass bowl.
Compared with prior art, beneficial effects of the present invention are：
A kind of interactive device of demonstrating current magnetic effect of the present invention, changes the big of coil block electric current by adjusting pressure regulator
It is small, so as to change the size in magnetic field produced by electric current；Motion of the clip being provided with by observing in transparent bowl in magnetic field
Situation, it was confirmed that electric current generates magnetic field around it；Phenomenon is obvious, vivid and interesting.
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；
Fig. 3 is side structure schematic view of the present invention.
Embodiment
Referring to shown in accompanying drawing 1-3, a kind of interactive device of demonstrating current magnetic effect, including stage body 1 and it is located at the stage body 1
On caging bolt 2, on the caging bolt 2 is coil block 3, and described coil block 3 is connected by pressure regulator 4
Power supply is connected to, protective cover 5 is provided with the described outside of coil block 3, transparent bowl 6 is provided between described coil block 3,
Multiple clips 7 are provided with described transparent bowl 6.
Preferably, described transparent bowl 6 is transparent acrylic glass bowl.
Mode of operation and principle are：Operator changes the size of the electric current of coil block 3 by adjusting pressure regulator 4, so that
The size in magnetic field produced by changing electric current；The clip 7 being placed in transparent bowl 6 can stand up in magnetic field.It is most of
Back-shaped 7 pin can be moved upwards up to the edge of transparent bowl 6.If the intensity in the magnetic field that increases sharply, some clips 7 even can be with
Stood up in the centre of modified line coil assembly 3.In this course, all clips 7 can attract each other as small magnet
Adhesion, when turning off electric current, clip 7 can fall back to the bottom of transparent bowl 6.Apparatus of the present invention are set by observing in transparent bowl 6
Motion conditions of some clips 7 in magnetic field, it was confirmed that electric current generates magnetic field around it；Phenomenon is obvious, vivid and interesting.
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.
