PURPOSE: A contactless charging portable terminal including a magnet detection function is provided to warn a user against a magnetic field through a warning unit by detecting the magnetic field. CONSTITUTION: When the first coil(3) of a charging pad(2) is approached to a predetermined distance, a second coil(10) in conjunction with the first coil charges a battery(50) by generating an induced electromotive force. A magnetic sensor(20) detects magnetic field radiated from a charging pad. When the magnetic sensor detects the magnetic field, a warning unit(30) generates warning. |
