ELECTRICAL PROPERTIES & SURFACE MORPHOLOGY STUDY ON MAGNETIC COMPOSITE FOR ROTATION COIL SENSOR APPLICATION

Abstract

Magnetic composite is widely used in technology now. Among the technology involves sensors and one of the many type of sensors is rotating coil sensors. On the other hand, the research on characterization of magnetic composite used is rotating coil sensors is lack of information. The research is done using three main method to obtain data. First is sample preparation. The sample is clean, cold mounting then grind. Next, the samples characterize using Scanning Electron Microscope (SEM), Energy-Dispersive X-Ray Spectroscopy (EDX) and ImageJ software. Then, the electrical properties of the sample. All the data is to determine the optimum parameter of the magnetic composite. The research conclude that as the number of porous count increases, the value of current flow also increases.
