The demonstration device comprises a support (1), a first horseshoe (2), a second horseshoe (3), a U-shaped frame (4), a batten (5), a coil (6) and a binding post (7). The demonstration device is characterized in that: the first horseshoe (2) and the second horseshoe (3) are respectively arranged at two sides of the support (1). The U-shaped frame (4) is arranged in the first horseshoe (2). The coil (6) is arranged in the second horseshoe (3) placed on the batten (5). The beneficial effects of the demonstration device are that: the structure is simple, the practicality is strong, when the demonstration device is used for experiments, enjoyment can be enhanced, attractive effects are generated, the new lesson introducing method of situation creation, question induction and extension development can lower the knowledge difficulty of a textbook, and the teaching effects of a lesson are strengthened.
Description
Technical field
The utility model belongs to physical teaching aid technical field, is specifically related to the effect apparatus for demonstrating of magnetic field to electrified wire.
Background technology
Junior physics experiment is the important method that student understands, studies the natural law, it is the basis of whole physics teaching, it is the main path of cultivating student's hands-on and thinking ability, also be the effective means that help student understands physics key concept, ultimate principle, the forward position of quality-oriented education and innovative education and the basis of basic educational reform, precondition and guarantee especially.Leave experimental teaching, the physics teaching reform of substance, essence of being just far from being, let alone implement in full quality-oriented education and advance the reform of fresh course.Therefore, experiment is the important component part of physics teaching, is the important step that improves junior middle school physics teaching quality, and in physics teaching, tool is of great significance.Experimental teaching is discharged the lower junior high school, rural area of rate from and is analyzed, inquires into experimental teaching present situation, and positive facilitation is got in the raising that will discharge rate to our junior physics experimental teaching.
Because physical and chemical experiment and current techique practice, in conjunction with carrying out, can creativeness be carried out current techique teaching, can promote again the experimental teaching of physics and chemistry fresh course; Designing Self-made Realia can cultivate student's innovation ability, improve its comprehensive attainment, homemade various teaching aid can supplement again the deficiency of existing instrument, so teaching aid that current techique practice and physics, Physical Experiment innovation realization are merged, it has embodied the design concept of current techique, green physics theory and physical knowledge principle, has really reached material and has been easy to get, makes simple, environmental protection, is easy to the standard promoted.This teaching aid is suitable for student to be made personally, to cultivate its innovation and integrated practice ability.
In the new class mark of junior physics grade eight volume two " motor " joint, " effect of magnetic field to electrified wire " teaching material has arranged two lecture experiments: electrified wire is subject to power in magnetic field and hot-wire coil reverses in magnetic field.Wherein the former is according to the method demonstration of teaching material, and visibility is little; The latter is because winding wire and the support frictional resistance that contacts is larger, demonstration DeGrain.For this this two experiments improve, and be made on a support, increased visibility by after improving, demonstration effect is also very obvious.
Summary of the invention
It is a kind of simple in structure, practical that the purpose of this utility model will provide exactly, can increase visibility, the effect apparatus for demonstrating of the magnetic field of demonstration successful to electrified wire.
The utility model is achieved through the following technical solutions:
The effect apparatus for demonstrating of magnetic field to electrified wire, comprises support 1, the first horseshoe 2, the second horseshoe 3, U-shaped frame 4, flitch 5, coil 6 and binding post 7, it is characterized in that: on described support 1, both sides are respectively equipped with the first horseshoe 2 and the second horseshoe 3; Described U-shaped frame 4 is located in the first horseshoe 2, is placed in the second horseshoe 3 on flitch 5 and is provided with coil 6.
On described U-shaped frame 4 and coil 6, be equipped with binding post 7.
Compared with prior art, the beneficial effects of the utility model are:
The teaching aid of the article assembled configuration complexity such as support 1, the first horseshoe 2, the second horseshoe 3, U-shaped frame 4, flitch 5, coil 6 and binding post 7 that the utility model provides, compare with experimental facilities in the past, reached material and be easy to get, make simple, a multi-purpose instrument.And in daily experiment, this teaching aid can use continuously, pollution-free, simple in structure, can use on a large scale popularization, and meet " green experiment " theory, simplify experimentation, the presentation process that it is vivid, makes whole teaching process effect remarkable, has greatly promoted the aspiration to knowledge of student's Scientific exploration.
The beneficial effects of the utility model are: simple in structure, practical, and the utility model is while testing with it, can strengthen interest, can produce fascinating effect, thisly found situation, bring out problem, extend the method for expanding, introduce new class and can reduce the knowledge difficulty on teaching material, strengthen the teaching efficiency of this class.
Brief description of the drawings
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In figure: support 1, the first horseshoe 2, the second horseshoe 3, U-shaped frame 4, flitch 5, coil 6, binding post 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
The effect apparatus for demonstrating of magnetic field to electrified wire, comprises support 1, the first horseshoe 2, the second horseshoe 3, U-shaped frame 4, flitch 5, coil 6 and binding post 7.
As shown in Figure 1, on its medium-height trestle 1, both sides are respectively equipped with the first horseshoe 2 and the second horseshoe 3, and U-shaped frame 4 is located in the first horseshoe 2, are placed in the second horseshoe 3 on flitch 5 and are provided with coil 6.
Wherein on U-shaped frame 4 and coil 6, be equipped with binding post 7.
The utility model, in the time of concrete use, on binding post 7, and is connected in the middle of the first horseshoe 2 cylinder of U-shaped frame 4 wire, switch, power supply (available two joint dry cells) series connection.Switch on power, change electric power polarity or change the magnetic pole of the first horseshoe 2, can be used to demonstrate electrified wire stressed and situation of motion in magnetic field.
The same on wire, switch, power supply (available two joint dry cells) series connection binding post 7, and coil 6 is positioned in the middle of the second horseshoe 3 of horizontal positioned.Switch on power, change electric power polarity or change the magnetic pole of the second horseshoe 3, can be used to demonstrate hot-wire coil stressed and situation of reversing in magnetic field.
