Abstract
The utility model relates to a device for displaying the movement of charged particles, which is suitable to be used as demonstration experiment in the class of middle school in order to make up the defect that the simple demonstration experiment for the movement of the charged particles in the electric field is lacked in the physics class. The device is also convenient for students to realize collective observation. The device adopts the following technical proposal: a small foamy ball moves back and forth between two charged metal sheets to simulate the movement of the charged particles in the electric field, thereby simplifying experimental apparatus and process.
Description
Technical field
The utility model relates to a kind of device that shows the charging particle movement phenomenon, is applicable in the classroom, middle school as lecture experiment.
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, adopt 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 explaining before the demonstration, phenomenon is also lively inadequately directly perceived, more is unfavorable for the collective of students observation of whole class.When therefore 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, so always there is a kind of knowledge not have the sensation that is relied at the blackboard upper plate.
Summary of the invention
In order to remedy this shortcoming of simple lecture experiment of the motion phenomenon of shortcoming charged particle in electric field in the physics classroom, being convenient to the student simultaneously can collective observe.The utility model adopts a macroscopical electric globule simulation microcosmic charged particle, simplifies experiment equipment and experimentation greatly, allows the motion phenomenon of teaching demonstration charged particle in electric field becomes convenient in the classroom.
The concrete technical scheme of the utility model is: an aperture is respectively opened at long plastic tank (also can being bonded with the plastic tank of two openings) two ends of about 20cm of two ends sealing, inboard, plastic tank two ends is fixed two sheet metals respectively, and its size is slightly less than the bottom size of jar.Each sheet metal is all drawn lead from jar two ends aperture, places the foam bead of an about 2cm size of diameter in the plastic tank, and foam bead outsourcing one deck tinfoil paper makes it can be with more static.Place insulating property preferably on the cystosepiment whole plastic tank level, and two the two poles of the earth that lead is received electrizer respectively will drawing.Under the experimental situation of drying, hand electrizer turning handle, to see that the foam bead is to a nearer relatively sheet metal motion, after the contact with going up the electric charge identical with this piece sheet metal, again with counter motion to another piece sheet metal, thereby the formation to-and-fro movement, and the speed of motion changes with electrizer turning handle change in rotational speed.If plastic tank is vertically placed, the phenomenon that the foam bead suspends at electric field can take place in the rotating speed of control electrizer turning handle.
Successful part of the present utility model is to adopt 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, and image is represented the motion phenomenon of charged particle in electric field incomparable effect.Practice is used, and this experimental demonstration is helpful to improving classroom atmosphere, even can test as the class that draws of problem.
Description of drawings
Below in conjunction with accompanying drawing and concrete experimental procedure the utility model is further specified.
Figure is an embodiment principle schematic of the present utility model.
1. electrizer the two poles of the earth among the figure, 2. lead, 3. sheet metal, 4. plastic tank, 5. bead, 6. cystosepiment
Embodiment
An aperture is respectively opened at plastic tank 4 two ends that about 20cm of closed at both ends is long, and inboard, plastic tank two ends is fixed two sheet metals 3 respectively.Each sheet metal 3 is all drawn lead 2 from jar two ends aperture, places the foam bead 5 of an about 2cm size of diameter in the plastic tank 4, and foam bead 5 outsourcing one deck tinfoil paper make it can be with more static.
Place insulating property preferably on the cystosepiment 6 whole plastic tank 4 levels, and two leads 2 will drawing the two poles of the earth 1 of receiving electrizer respectively.Under the experimental situation of drying, hand electrizer turning handle, to see that bead 5 is to a nearer relatively sheet metal 3 motions, after the contact with going up the electric charge identical with this piece sheet metal 3, again with counter motion to another piece sheet metal 3, thereby the formation to-and-fro movement, and the speed of motion changes with electrizer turning handle change in rotational speed.If plastic tank 4 is vertically placed, the phenomenon that foam bead 5 suspends at electric field can take place in the rotating speed of control electrizer turning handle.
Claims (1)
1, a kind of charging particle movement demonstrator, it is characterized in that: with the long plastic tank of about 20cm of two ends sealing, an aperture is respectively opened at two ends, inboard, plastic tank two ends is fixed two sheet metals respectively, its size is slightly less than the bottom size of jar, each sheet metal is all drawn lead from jar two ends aperture, two the two poles of the earth that lead is received electrizer respectively of drawing, place the foam bead of an about 2cm size of diameter in the plastic tank, foam bead outsourcing one deck masking foil, whole plastic tank level place insulating property preferably on the cystosepiment.
