Description

The motion visualizer of charged particle in electric field

Technical field

The utility model relates to a kind of visualizer, particularly relates to the motion visualizer of a kind of charged particle in electric field, belongs to technical field of teaching instruments.

Background technology

The motion phenomenon of charged particle in electric field is a key content of physics teaching in secondary school; But because the motion of the microscopic particle often that relates to, the middle school physical experiment chamber does not almost have suitable experimental demonstration device at present, adopts cloud chamber to show the movement locus of particle; Not only require very high to experiment equipment; And needing more loaded down with trivial details operation before demonstrating, the phenomenon of generation is also lively inadequately, directly perceived, is unfavorable for that more the student of whole class carries out collective's observation.Therefore, when the teacher carries out the teaching of this content at present, generally can only rely on multimedia to simulate, even can only draw the explanation of cooperation language at the blackboard upper plate, so, always there is a kind of knowledge not have the sensation that is relied on.

Summary of the invention

The utility model technical matters to be solved is, overcomes defective of the prior art, and a kind of this shortcoming of simple lecture experiment that remedies the motion phenomenon of shortcoming charged particle in electric field in the physics classroom is provided, and is convenient to the instrument that the student can collective observes simultaneously.

The technical scheme that the utility model adopted is; The motion visualizer of a kind of charged particle in electric field; Comprise; Glass spheres, glass spheres support, plane-parallel capacitor, plane-parallel capacitor support, pointer dial, single-pole triple-throw (SPTT) switch, electric battery and length scales; Described glass spheres is arranged on the described glass spheres support, and described length scales and plane-parallel capacitor are arranged on the described plane-parallel capacitor support, and described electric battery is electrically connected with described glass spheres and described plane-parallel capacitor respectively through described single-pole triple-throw (SPTT) switch each other.

Described glass spheres is the glass spheres of hollow, and the glass bead upper body is provided with a through hole that connects glass medium, and the surfaces externally and internally of glass spheres is the conductive layer of mutually insulated; Described pointer dial and described plane-parallel capacitor are separately positioned on the described plane-parallel capacitor support.

Described glass spheres support, length scales and described plane-parallel capacitor support are the insulation material.

The utility model beneficial effect be; Owing to adopt a macroscopical electric globule simulation microcosmic charged particle; Simplify experiment equipment and experimentation greatly, the motion phenomenon of macroscopical electric globule obviously is easy to observe, and image is represented the motion phenomenon of charged particle in electric field has incomparable effect; This experimental demonstration is to the students understand content of courses, and it is helpful to improve classroom atmosphere.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Fig. 1 is the enlarged diagram of the utility model glass spheres; Fig. 2 is the motion visualizer principle schematic of the utility model charged particle in electric field.As depicted in figs. 1 and 2; The utility model comprises; Glass spheres 10, glass spheres support 20, plane-parallel capacitor 30, plane-parallel capacitor support 40, pointer dial 50, single-pole triple-throw (SPTT) switch 60, electric battery 70 and length scales 80; Described glass spheres 10 is arranged on the described glass spheres support 20; Described length scales 80 is arranged on the described plane-parallel capacitor support 40 with plane-parallel capacitor 30, and described electric battery 70 is electrically connected with described plane-parallel capacitor 30 with described glass spheres 10 respectively through described single-pole triple-throw (SPTT) switch 60 each other.

Described glass spheres 10 is the glass spheres of hollow, and the glass bead upper body is provided with a through hole that connects glass medium, and the surfaces externally and internally of glass spheres is the conductive layer of mutually insulated; Described pointer dial 50 is separately positioned on the described plane-parallel capacitor support 40 with described plane-parallel capacitor 30.

Described glass spheres support 20, length scales 80 and described plane-parallel capacitor support 40 are the insulation material.

During the utility model demonstration; Positive pole with electric battery is connected with the conductive layer of the inside surface of glass spheres earlier; Make the inside surface of glass spheres have electric charge; Rotation single-pole triple-throw (SPTT) switch makes the positive pole of electric battery be connected with the positive plate of plane-parallel capacitor, and plane-parallel capacitor is recharged, and rotation single-pole triple-throw (SPTT) switch makes the anodal unsettled of electric battery; To have the electric charge glass spheres then uses the insulation clip to be placed between the plane-parallel capacitor two-plate that is recharged; The motion conditions of observational study electric globule under electric field and gravity field acting in conjunction, length scales can be adjusted the distance between the plane-parallel capacitor two-plate, the angle of inclination that pointer dial can the observational study plane-parallel capacitor.

The utility model adopts a macroscopical electric globule simulation microcosmic charged particle; Simplify experiment equipment and experimentation greatly; The motion phenomenon of macroscopic view electric globule obviously is easy to observe; Image is represented the motion phenomenon of charged particle in electric field has incomparable effect, and this experimental demonstration is to the students understand content of courses, and it is helpful to improve classroom atmosphere.Simplify experiment equipment and experimentation greatly, let the motion phenomenon of teaching demonstration charged particle in electric field becomes convenient in the classroom.

It is worthy of note; The protection domain of the utility model is not limited to above-mentioned instantiation mode; According to the basic fundamental design of the utility model, also available essentially identical structure can realize the purpose that this is novel, as long as those of ordinary skills need not through creative work; The embodiment that can associate all belongs to the protection domain of the utility model.
