This paper investigates the parameters influencing the efficiency of wireless transmission of electrical power using the Near Field technique. The study is divided into two main parts: theoretical verification and experimental construction. In the theoretical verification, the magnetic field intensities generated by different circular loops at various axial distances are calculated using the Biot-Savart law and compared with theoretical predictions. The experimental construction involves constructing coils with varying radii and measuring the resulting magnetic field intensities and resonant frequencies. Additionally, curved solenoids with magnetizable cores and capacitive plates are built to investigate power transfer distances. The results provide empirical evidence regarding the efficiency and feasibility of wireless power transmission using the Near Field technique. This research contributes to the advancement of wireless power transfer technologies and offers insights into optimizing efficiency in wireless power transmission systems.
