Abstract
The utility model discloses a teaching experiment device of demonstration electricity generation principle, this teaching experiment device include the base, are fixed in two corresponding support arms on the base, the upper end of two support arms is passed through the crossbeam and is connected, hang a swing arm on the crossbeam, an arc magnet is connected to the lower extreme of swing arm, is equipped with the electricity generation coil on the base of crossing of one of them support arm and base, and the electricity generation coil links to each other with small bulb. Owing to adopt above -mentioned structure, through the demonstration, can make that the student is very visual in image to understand the electromagnetic induction principle, excite student's interest in learning, improve the classroom teaching effect.
Description
Technical field
The utility model relates to a kind of teaching demonstration device, particularly relates to a kind of experiment device for teaching demonstrating electricity generating principle.
Background technology
In current teaching, due to electricity and the magnetic line of force be all cannot see touch less than thing, be a teacher when explaining electromagnetic induction principle, for the student just contacting electromagnetism, indigestion, teacher is also difficult to image, lively explanation, this brings certain difficulty to teaching, in order to student can be allowed to carry out theories of learning knowledge by macroscopic appearance, we are in teaching for many years, have devised a kind of experiment device for teaching demonstrating electricity generating principle.
Summary of the invention
The purpose of this utility model be to provide a kind of can the experiment device for teaching of demonstration electricity generating principle of lifelike image.
The purpose of this utility model is achieved through the following technical solutions, the sway brace that this experiment device for teaching comprises base, two of being fixed on base are corresponding, the upper end of described two sway braces is connected by crossbeam, described crossbeam hangs a swing arm, the lower end of described swing arm connects an arc-shaped magnet, the base of a sway brace and base intersection is provided with power coil wherein, and power coil is connected with miniature bulb.
According to electromagnetic induction principle, when the arc-shaped magnet swing of this device, the magnetic line of force of arc-shaped magnet cut by power coil, the electric current of generation makes miniature bulb shinny.
The beneficial effects of the utility model: owing to adopting said structure, by demonstration, the understanding electromagnetic induction principle that student is very visual in image can be made, motivate students' interest in learning, improve classroom teaching effect.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is schematic diagram of the present utility model
In figure: 1, base 2, sway brace 3, crossbeam 4, swing arm 5, arc-shaped magnet 6, power coil 7, miniature bulb
Embodiment
As shown in Figure 1, the sway brace 2 that this experiment device for teaching comprises base 1, two of being fixed on base 1 are corresponding, the upper end of two sway braces 2 is connected by crossbeam 3, crossbeam 3 hangs a swing arm 4, the lower end of swing arm 4 connects an arc-shaped magnet 5, the base of right support arm and base 1 intersection is provided with power coil 6, and power coil 6 is connected with miniature bulb 7.According to electromagnetic induction principle, when arc-shaped magnet 5 swing, the magnetic line of force of arc-shaped magnet 5 cut by power coil 6, the electric current of generation makes miniature bulb 7 shinny.
