The composite of CNT–Fe were made by mixing CNT and Fe powder with the variance of Fe starting from 3% and 5% weight. Then the sample is milling for 2 hours using High Energy Milling (HEM). The CNT-Fe Composite to be had done implantasion with nitrogen gas for 5 hour and 8 hour. The result of magnetic parameter of composite CNT-Fe3% and CNT-Fe5% with VSM (Vibrating Sample Magnetometer) method shows that the remanent magnetic (Mr) and saturation magnetic (Ms) increased, and the coersive magnetic (Hc) decreased with the increasing of weight percent of Fe. The result of electrical properties of composite CNT-Fe3% and CNT-Fe5% using LCR instrument indicated that conductivities value of composite CNT-Fe3% and MWCNT-Fe5% are increased with the increasing of Fe weight. The surface morphology of composite CNT-Fe3% and CNT-Fe5% was done with TEM (Transmition Electron Microscopy) with the result that Fe was had into CNT.
