Description
Technical field
The present invention relates to Popular Science Education technical field more particularly to a kind of simple teaching aids of the raw electrical phenomena of demonstration magnetic.
Background technique
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 the 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 of raw electrical phenomena of demonstration magnetic is devised.
Summary of the invention
The purpose of the present invention is to provide a kind of teaching aids of easy raw electrical phenomena of demonstration magnetic, and teaching can be facilitated to promote.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of simple teaching aid of the raw electrical phenomena of demonstration magnetic, is protected including stage body and the ammeter being located on the stage body and coil
Set, the coil jackets be ring structure, be between the great circle and roundlet of ring structure it is hollow, it is hollow it is interior be wound with coil,
The coil is connected and is formed into a loop with the ammeter, is equipped with bar magnet, the bar magnet in the center of the coil jackets
It is mounted in transparent handle.
Compared with prior art, the invention has the benefit that
A kind of simple teaching aid of the raw electrical phenomena of demonstration magnetic of the present invention, the magnetic field generated by bar magnet is in the annular that coil is housed
Structure coil sheath internal cutting generates electric current, and the electric current of generation is shown in ammeter, to prove depositing for electromagnetic induction phenomenon
?.The characteristics of teaching aid of the present invention is that structure is simple, and it is very clear to demonstrate, and be should be readily appreciated that.
Detailed description of the invention
Fig. 1 is schematic diagram of main cross-sectional structure of the present invention；
Fig. 2 is overlooking structure diagram of the present invention.
Specific embodiment
Referring to shown in attached drawing 1-2, a kind of simple teaching aid of the raw electrical phenomena of demonstration magnetic, including stage body 1 and it is located at the stage body 1
On ammeter 2 and coil jackets 3, the coil jackets 3 be ring structure, be wherein between the great circle and roundlet of ring structure
It is hollow, it is hollow it is interior be wound with coil 4, the coil 4 is connected and is formed into a loop with the ammeter 2, in the coil jackets 3
Center be equipped with bar magnet 5, the bar magnet 5 is mounted in transparent handle 6.
Steps are as follows for teaching aid demonstration operation:
1. bar magnet 5 to be put into the middle position of coil 4, keep its stationary, observes 2 registration of ammeter, at this time ammeter 2
Without registration；
2. bar magnet 5 is taken out from coil 4,2 registration of ammeter is observed in the moment taken out, discovery ammeter 2 has registration；
3. observing 2 registration of ammeter by bar magnet 5 after taking out in coil 4, find without registration；
4. bar magnet 5 to be put into the middle position of coil 4 from outside, in the moment being put into, 2 registration of ammeter, discovery are observed
There is registration.
A kind of simple teaching aid of the raw electrical phenomena of demonstration magnetic of the present invention, the magnetic field generated by bar magnet 5 is in the ring that coil 4 is housed
3 internal cutting of shape structure coil sheath generates electric current and shows in ammeter 2, to prove the presence of electromagnetic induction phenomenon, this hair
The characteristics of penetrating judgment has is that structure is simple, and it is very clear to demonstrate, and be should be readily appreciated that.
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.
