A position alignment method, performed by a vehicle assembly (VA) including a reception pad receiving power transmitted from a transmission pad of a ground assembly (GA) is provided. The method includes transmitting a magnetic field using a transmitting device disposed on a reception pad, the transmitting device operating with low frequency (LF); receiving a magnetic field related value from the GA, the magnetic field being detected by an LF receiving device disposed on the transmission pad of the GA; and calculating, by a controller, a distance between the transmission pad and the reception pad using the magnetic field related value. A part of the transmitting device is disposed to arrange a magnetic field formed by the part of the transmitting device in a 0°, 90°, 180°, or 270° direction with respect to a magnetic field formed by a part of the LF receiving device.
