Abstract: An electronic device (e.g., a power supply device or a power receiving device) includes a housing including a first side of the electronic device and a second side opposite to the first side, a wireless charging coil disposed in the housing, and a magnet structure disposed in the housing to surround the coil and including a plurality of magnet pieces including a first magnet piece and a second magnet piece. The first magnet piece includes a first outer magnetized area having an N pole facing the first side, a first inner magnetized area disposed closer to the coil than the first outer magnetized area and having an S pole facing the first side, and a first non-magnetized area disposed between the first outer magnetized area and the first inner magnetized area. The second magnet piece includes a second outer magnetized area having an N pole facing the first side, a second inner magnetized area disposed closer to the coil than the second outer magnetized area and having an S pole facing the first side, and a second non-magnetized area disposed between the second outer magnetized area and the second inner magnetized area. The first magnet piece has a first magnetic force and the second magnet piece has a second magnetic force different from the first magnetic force.
