Magnetic flux leakage from an AC adapter or a notebook PC can be recovered by using a coil. However, because the magnetic flux that leaks out is very small, the power that can be collected by a coil is small. As a result, the quality factor of the coil must be increased to increase the power that can be collected by the coil. The use of magnetoplated wire (MPW) to from the coil can reduce the resistance due to the proximity effect in comparison with the use of copper wire (COW). MPW is a COW that has a circumference that is plated with a magnetic thin film. In this paper, we investigate the energy harvesting by a coil consisting of MPW. We used a coil with an outer diameter of 9.9 mm and 300 turns. The quality factor of the leakage flux recovery coil using COW and MPW at a frequency of f = 250 kHz was 119 and 135, respectively, and it is increase in 13.4% by using MPW.
