Magneto-impedance (MI) multilayer [Ni80Fe20 (800 nm)/Cu (300 nm)]3 in Cu wire has been modified in its geometric shapes. The Multilayer is the result of electro-deposition with Pt (platinum) as the electrode. This study shows that the MI ratio changes to the geometry of the sample. The geometry modification increases the MI ratio of 54.35% (wire shape) amounted to 70.53% (solenoid shape); it is measured at a frequency of 100 kHz. The modification also increase the sensitivity sensor magnetic from 9.05%/mT to 12.82%/mT.
