Background technology
H. C. Oersted Experiment make people for the first time recognize electrically and magnetically between close ties, for manufacture motor established reason
By basis.From teaching, can carry out H. C. Oersted Experiment be the key that can student learn electromagnetism well.But teaching material is tested to this
Design effect and unobvious, with wire by the both positive and negative polarity of battery be directly connected to and be placed on demonstration needle top, it is found that magnetic
The deflection of low-angle occurs for pin.Points for attention are more during experimental implementation, must lead to stronger electric current in wire and the time not
Can be oversize, the necessary north-south of wire is placed, the relation of magnetic direction and the sense of current.Teacher should explain experiment in presentation process
It is required that organizing the student observation again, also want operation experiments often in a rush.
The content of the invention
The purpose of this utility model is to provide a kind of H. C. Oersted Experiment demonstration device, is deposited in the prior art so as to efficiently solve
The problem of.
To realize that the purpose of this utility model adopts the technical scheme that：A kind of H. C. Oersted Experiment demonstration device, its feature exist
In：Base（1）One end center is provided with poly (methyl methacrylate) plate（2）, the other end is provided with two binding posts（9）, the position switch of triangle three（10）
With the position switch of hexagonal three（11）；Poly (methyl methacrylate) plate（2）Center is provided with pillar（5）, pillar（5）Top is provided with needle（6）；Lucite
Plate（2）Both sides are respectively equipped with conducting bracket, and the conducting bracket is by bottom cross bar（4）And vertical pole（3）Vertical hinge connection composition, bottom
Cross bar（4）And vertical pole（3）It is provided with multiple LEDs（8）, vertical pole（3）On set up heavy gauge wire（7）, heavy gauge wire（7）Positioned at magnetic
Pin（6）Surface；Base（1）The back side is provided with circuit system.
The bottom cross bar（4）And vertical pole（3）For aluminium alloy frid, groove is interior to lay electric wire.
The pillar（5）For telescopic mast；The conducting bracket can fold.
The circuit system is：Flowing water circuit board is connected with battery case, and two kinds of color LEDs connect into positive and negative two-way, LED
Lamp is connected by hub with flowing water circuit board output end, the position switch of triangle three（10）The controlling stream water circuit sense of current is so as to changing
Become LED blinking sequences；Conducting bracket is connected by rotary screw with base lower wire, by the position switch of hexagonal three（11）The friendship of formation
Pitch circuit control, for control electric current direction and connecting and disconnecting of the circuit, red-black binding post respectively with the position switch of hexagonal three（11）Centre
Two corners are connected as conducting bracket power supply.
The beneficial effects of the utility model are：Production process is simple, and material requested is easily prepared；Each element of demonstration device can be with
Folding is easy to mounted box to preserve；Rationally distributed, easy to operation, experimental phenomena is obvious, is capable of the relation of accurate reflection electricity and magnetic；
Save the time and improve efficiency, help student to understand the relation of electricity and magnetic well, established to establish the structure of knowledge of systems linking
Basis.

Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
1）Demonstration device is placed in horizontal table top, battery No. 5 dry cells of box-packed 3 section, 6V power positive cathodes are connected on binding post 9
On, switch side is close to oneself；
2）Pillar 5 is holded up, needle 6 is placed on it, when needle 6 is static, then conducting bracket is holded up, swinging mounting makes it
In the direction of needle 6, heavy gauge wire 7 is costed on conducting bracket；
3）Two switches are all placed in a gear, it is exactly the sense of current of heavy gauge wire 7 that LED, which lights order, observation needle 6 side of deflection
To.Switch is all placed in two gears again, LED is lighted when order is kept off with one on the contrary, being the sense of current of heavy gauge wire now.Observation is existing
As conclusion can be summarized.
4）After experiment, heavy gauge wire 7 and needle 6 on pillar 5, folding rack are removed, mounted box preserves.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
