Permeability Analysis of Fe2O3 Magnetic Core

Affordable high magnetic permeability material has always been a challenge for those who are working with RCD. This article tried to show the possibility of using the low cost Iron Oxide powder. This is because Fe₂O₃ is more available nowadays. The first work was trying to analyze Fe₂O₃ permeability using physics approaches. It was included the simulation using Abninit - a Density Functional Theory software. Then it discussed the test of the simple magnetic core using common household's AC voltage. From the test, 9.52 mV AC could be easily induced from 230 V AC using the magnetic core with only sixteen windings at a low current of 13.21 mA.
