magnetization of this magnet was set to be 75,000 A/m as suggested from the data sheet [12], and the total magnetic flux from the simulation was estimated as ~ 63 µWb. To achieve the same amount of the magnetic flux in a single-turn loop, the needed current is about 3.5 kA. In an experiment, the system was able to deliver 2.969 W at operating a low frequency of 180 Hz to a load resistor of 117.1 Ω over the transfer distance of 1 cm with overall the efficiency of 50 %. However, in high power applications the surface of magnet need to be much that is difficult to control the magnetic field around the surface of magnet.
