According to an embodiment of the present invention, a wireless charging system comprises: a charging terminal including a magnet and a transmission coil for transmitting a magnetic field to a charged terminal; and the charged terminal including a reception coil for generating a current after receiving the magnetic field from the transmission coil. After detecting the charging terminal arranged close to the charged terminal and until wireless charging is initiated, the charged terminal utilizes the reception coil as an electromagnet for generating magnetic flux in order to recognize a wireless charging mode. As a result, the wireless charging system can eliminate bad effects of an external device caused by a permanent magnet without additional cost. |
