Simple detection device for induction currents using Lorentz force principle based on c-945 transistors

摘要

With this simple material, this research can create a simple tool to detect an induction current based on transistor c-945 with a pointer indicator using LED lights that aims to determine the location of the breaking point (not flowing induction current) that contains the Lorentz force principle and calculates the distance of induction current drops against this tool. The method used in this research is qualitative and quantitative methods. The qualitative method can be obtained by the success of the LED lights that are on if there is an induced current flowing and the LED will turn off if there is no induction current flowing. Quantitative methods obtain data from the measurement of the distance of the induced current to the device both horizontally and vertically. This data collection process is carried out by varying the load on the outlet then reviewing the power cables that have been connected by AC power sources. From the results of the study it was found that this tool is able to make the LED lights on if there is an induction current flowing and the LED lights will die if there is no induction current on the power cord. Whereas in other data obtained the distance detected induction current on the cable to this tool [horizontally-vertically] namely [(4.0±0.5)-(4.0±0.5)] mm with no load, [(6.0±0.5)-(4.0±0.5)] mm with 1 load, [(7.0±0.5)-(1.0±0.5)] mm with 2 loads, [(8.0±0.5)-(1.0±0.4)] mm with 2 loads, and [(6.0±0.5)-(2.0±0.5)] mm with 4 loads.
