[0002] The electrostatic field tracing instrument is an experimental teaching instrument developed for different types of electrostatic fields in physical experiments. The experiment mainly uses the distribution of the steady current field in the conductor to simulate the distribution of the electrostatic field. The old-fashioned electrostatic field tracing instrument mostly uses conductive Paper or water is used as a conductor for manual detection and positioning of the probe. In the former method, due to the uneven thickness of the graphite layer on the conductive paper and the uneven contact between the electrode and the conductive paper, the drawn electric field is related to the expected one. far
In the latter method, it is required that the upper and lower probes must be coaxial to better describe the simulated electrostatic field. However, in actual use, because the long thin copper sheet supporting the two probes is easily deformed, the upper and lower probes Severely misaligned and unable to be coaxial, the trace error is too large, which seriously affects the experimental results
