  "textContent": "A wireless power transmission apparatus for induction heating includes a working coil configured to change a mode depending on selection of a user, to vary an operation frequency depending on the mode and to induction-heat a target object, or to wirelessly transmit power to the target object, an inverter that is turned on and off depending on the operation frequency and configured to generate the power, and a controller configured to determine whether a foreign object is positioned on the working coil over a plurality of modes in a preparation period prior to wireless power transfer (WPT) when the user selects a wireless power transmission mode. Thus, a multi-functional wireless power transmission device using one working coil detects whether a foreign object is present, compensates for this, and performs WPT in a wireless power transmission mode while selectively driving a wireless power transmission mode or an induction heating mode.",
