  "textContent": "A wireless power transmission apparatus for induction heating includes: a working coil configured to change operation based on selection of a mode of operation from among a plurality of operating modes, the plurality of operating modes including a wireless power transmission mode configured to wirelessly transmit power and a heating mode configured to heat one or more objects, an inverter configured to output, to the working coil, current at an operation frequency, and a controller. The controller is configured to receive, in the wireless power transmission mode, a load voltage from a target object, compensate for the load voltage, and determine, in the wireless power transmission mode, whether a foreign object is present in the working coil based on the compensated load voltage.",
