According to various embodiments of the present disclosure, an electronic device comprising: a housing; a conductive pattern that is provided in the housing; and a controller that is electrically connected with the conductive pattern, configured to apply a current to the conductive pattern, monitor the current, and if the monitored current value exceeds a first threshold value for more than a selected time, changes the current value to a first selected value that is equal to or less than the first threshold value; wherein the conductive pattern is configured to generate induced electric power responsive to application of current by the controller. Various embodiments may be provided.
