Recently, generation of electrical power from the oceanic wave draws incredible attention to the researchers and engineers. Although, oceanic wave energy is gigantic and available to most of the earth's surface, it is still unused because of the lack of technological excellence in the past decades. Therefore, research gap is created in this regard specially extraction of electrical power from the oceanic wave. In this paper, wave energy devices and optimization of the linear electrical generator (LEG) that mainly converts the mechanical energy (from the device) into electricity are presented in detail with finite element analysis (FEA). The methodology involves analysis of the design, observation of its electrical and magnetic properties, optimization, different copper windings, enhancement of output power, maximizing the efficiency of the LEG, and power density. To test the proposed method, an LEG is designed using the computer aided design software. Its geometry is then imported
