Description
Technical field
The utility model relates to research and teaching instrument field, particularly a kind of earth magnetism power generation demonstrating device.
Background technology
The discovery of electromagnetic induction phenomenon is one of greatest achievement in electromagnetics field.When a part of conductor of closed circuit does cutting magnetic induction line motion, will generation current on conductor.It does not only disclose the inner link between electricity and magnetic, and has established experiment basis for the mutual conversion between electricity and magnetic, for the mankind obtain huge and the electric energy of cheapness opens road, is of great importance in practical.The discovery of electromagnetic induction phenomenon, indicates the arrival of a great industry and technological revolution.
The earth itself is a huge magnet, and in a certain place, when needle is static, place perpendicular is called the magnetic meridian plate in this place, and the intersection of magnetic meridian plate and surface level is magnetic meridian.Complete loop cutting magnetic induction line can produce induction current, when the magnetic induction line of complete loop cutting terrestrial magnetic field, also can generation current, and during wire perpendicular cuts magnetic meridian, the electric current of generation is maximum.
In research and teaching, need to carry out earth magnetism electrification demonstration with the existence of the announcement terrestrial magnetic field of image and electromagnetic induction phenomenon to student.But existing its function of earth magnetism electrification demonstration equipment is all more single, and bad operation.Prior art employing is hung a weight and is become pendulum on the copper wire of long 2-3 rice, and the upper and lower two ends of copper wire are respectively drawn with flexible circuit conductor and are connected with sensitive reometer, and weight is put to swing in terrestrial magnetic field, and earth magnetism generating is demonstrated in the change of observation ammeter pointer.Its technical scheme complicated operation, the beat of pointer is not obvious, and demonstrating effect is undesirable.
Utility model content
For above problem, the utility model patent object is to devise a kind of earth magnetism power generation demonstrating device, its easy to operate, demonstrating visual, and demonstrating effect is desirable.Technical solutions of the utility model are as follows:
A kind of earth magnetism power generation demonstrating device, comprise base (1) and fixed support (2), described base (1) is arranged on fixed support (2) by rotating mechanism (7), described fixed support (2) is vertically placed, described fixed support (2) is rotatablely equipped with connecting link (3), described connecting link (3) is connected with rotating frame (4), described rotating frame (4) is wound with coil (5), described coil (5) two ends connect micro-reometer (6).
Further, connecting link described in the utility model (3) is metallic copper bar.
Further, rotating mechanism described in the utility model (7) is circular, and described rotating mechanism (7) can drive described fixed support (2) to rotate in surface level.
Further, coil described in the utility model (5) is wound with 300-400 circle.
Accompanying drawing explanation
Referring to accompanying drawing, the utility model embodiment is described further, wherein:
Fig. 1 is the structural drawing of a kind of earth magnetism power generation demonstrating device of the utility model;
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model proposes a kind of earth magnetism power generation demonstrating device, refer to the structural drawing that Fig. 1 is a kind of earth magnetism power generation demonstrating device of the utility model, comprise base (1) and fixed support (2), described base (1) is arranged on fixed support (2) by rotating mechanism (7), described fixed support (2) is vertically placed, described fixed support (2) is rotatablely equipped with connecting link (3), described connecting link (3) is connected with rotating frame (4), described rotating frame (4) is wound with coil (5), described coil (5) two ends connect micro-reometer (6).
Described connecting link (3) is metallic copper bar, plays electric action for support rotating framework.
Described rotating mechanism (7) is circular, described rotating mechanism (7) can drive described fixed support (2) to rotate in surface level, in good time rotary fixed bracket, makes coil and magnetic direction deflect, and the change observing each directional current is strong and weak.
Described coil (5) is wound with 300-400 circle, and global design is closed-in construction, and handsome in appearance, structure is simple, easy to operate.
The above embodiment of the present utility model, does not form the restriction to the utility model protection domain.Any various other made according to technical conceive of the present utility model change and distortion accordingly, all should be included in the protection domain of the utility model claim.
