Simulation demonstrating apparatus of electric field line

Abstract

The invention relates to a simulation and demonstration device for electric field line in physics, comprising: an influence machine with a discharging fork arm, an insulated pad, as well as a cap made from a non-insulator with an insulation suspender; wherein the insulation suspender can be a linear suspender or an insulation paper; and the attached insulation suspender had best not touch each other. Because of the adoption of technology scheme above, human wearing the cap with attached insulation suspender and standing on the insulated pad for participating the simulation and demonstration has insulated by the influence machine; the charge aggregated by small balls on the discharging fork arm is continuously output to the cap and the insulation suspender, namely an insulation line or an insulation belt, through hands of the human for participating the simulation and demonstration, under the action of a force that the same charge is repellent with each other, the lighter insulation suspender, namely the insulation line or insulation belt, will be automatically distributed according to an electric line direction, and each insulation suspender standing up, which is a simulation and demonstration of the called ''bristle with anger''.

Description

technical field [0001] The present invention relates to a simulation demonstration device of electric field lines in physics, commonly known as "angry crown", specifically related to the first edition in 2003, which was printed for the seventh time in April 2005, and was reviewed by the National Middle School Textbook Approval Committee in 2002 Passed, edited by the Physics Office of the People's Education Press and published by the People's Education Press, the second volume of the full-time ordinary high school textbook "Compulsory Plus Elective", the section "Electric Field Lines" in Chapter 30 "Electric Field" (textbook pp. 124-125) for a simulated demonstration of the experimental setup (see Figure 4 on the front page of the textbook).

[0002] The experiment arranged in the textbook is actually a simulation demonstration device of electric field lines, commonly known as "the furious crown". Although the purpose of the experiment is clear, the experiment is intuitive, and life-like, it is easy to stimulate students' interest in learning, but the "furious crown" experiment in the textbook It’s just a picture. In real life, it can only be realized in museums and science and technology museums. If you really want to realize the phenomenon of “angry rushing to the crown”, the induction generator must reach at least hundreds of thousands of volts of electrification voltage, while the existing ones in general middle schools The induction motor can only generate a voltage of tens of thousands of volts, so it cannot meet this technical requirement, and the experiment is impossible to talk about, so it is difficult to realize it in ordinary middle schools.
