Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of simple teaching aid for demonstrating magnetic life electrical phenomena.
Background technology
Electromagnetic induction phenomenon is an important knowledge point of the student in learning process, there is many demonstrating electromagnetic inductions at present
The device of phenomenon occurs, but the apparatus for demonstrating of prior art is more abstract, and structure is complex, and the present invention is in simplification as far as possible
Under mentality of designing, a kind of simple teaching aid for demonstrating magnetic life electrical phenomena is devised.
The content of the invention
It is an object of the invention to provide a kind of teaching aid of easy demonstration magnetic life electrical phenomena, conveniently teaching can promote.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of simple teaching aid for demonstrating magnetic life electrical phenomena, including stage body and the ammeter and coil jackets that are located on the stage body,
The coil jackets are loop configuration, be between the great circle and roundlet of loop configuration it is hollow, it is hollow it is interior be wound with coil, it is described
Coil is connected with the ammeter and forms loop, and bar magnet, the bar magnet installation are provided with the center of the coil jackets
In transparent handle.
Compared with prior art, beneficial effects of the present invention are：
A kind of simple teaching aid for demonstrating magnetic life electrical phenomena of the present invention, by magnetic field caused by bar magnet in the loop configuration equipped with coil
Coil jackets internal cutting produces electric current, and caused electric current is shown in ammeter, so as to prove the presence of electromagnetic induction phenomenon.This
The characteristics of invention teaching aid is simple in construction, and demonstration is very clear, should be readily appreciated that.
Brief description of the drawings
Fig. 1 is main view cross section structure diagram of the present invention；
Fig. 2 is overlooking the structure diagram of the present invention.
Embodiment
Referring to shown in accompanying drawing 1-2, a kind of simple teaching aid for demonstrating magnetic life electrical phenomena, including stage body 1 and it is located at the stage body 1
On ammeter 2 and coil jackets 3, the coil jackets 3 are loop configuration, are wherein between the great circle of loop configuration and roundlet
It is hollow, it is hollow it is interior be wound with coil 4, the coil 4 is connected with the ammeter 2 and forms loop, in the coil jackets 3
Center be provided with bar magnet 5, the bar magnet 5 is arranged in transparent handle 6.
Teaching aid demonstration operation step is as follows：
1. bar magnet 5 to be put into the centre position of coil 4, make its transfixion, observe the registration of ammeter 2, now ammeter 2 is without showing
Number；
2. bar magnet 5 is taken out from coil 4, the registration of ammeter 2 is observed in the moment taken out, it is found that ammeter 2 has registration；
3. after bar magnet 5 is taken out from coil 4, the registration of ammeter 2 is observed, finds no registration；
4. bar magnet 5 to be put into the centre position of coil 4 from outside, in the moment being put into, the registration of ammeter 2 is observed, discovery, which has, to be shown
Number.
A kind of simple teaching aid for demonstrating magnetic life electrical phenomena of the present invention, by magnetic field caused by bar magnet 5 in the ring equipped with coil 4
The internal cutting of shape structure coil sheath 3 produces electric current and shown in ammeter 2, to prove the presence of electromagnetic induction phenomenon, this hair
The characteristics of penetrating judgment has is simple in construction, and demonstration is very clear, should be readily appreciated that.
It is described above, it is only the preferred embodiments of the present invention, not limits the present invention,
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 it is 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.
