This paper describes the design and analysis of vibration driven cylindric electromagnetic energy harvester. The proposed harvester consists with spring, coil and rear earth magnet. The design utilizes an electromagnetic transducer and its operating principle is based on the relative movement of a magnet pole with respect to a coil. In order to optimal design and analysis, ANSYS FEA (Finite Elements Analysis) and Matlab model were used to predict the magnetic filed density with vibration and the generated maximum output power with load resistance. The system was designed for 6 Hz of natural frequency and spring constant was 39.48 N/m between 2 mm and 6 mm of displacement in moving magnet. When moving magnet of system was oscillated, each model was obtained that induced voltage in the coil was generated 2.275 Vpp, 2.334 Vpp and 2.384 Vpp, respectively. Then maximum output powers of system at load resistance ($1303{Omega}$) were generated $124.2{sim}132.2;{mu}W$ during magnets input displacement of 3 mm and 6 Hz periodic oscillation.
