Original Abstract Submitted
an induction device includes: a wireless power transmission circuit; a current sensor; and at least one processor connected to the wireless power transmission circuit and the current sensor, wherein the at least one processor is configured to output first power for detecting of an external device through the wireless power transmission circuit, identify a first phase of a first current by measuring the first current flowing through a transmission coil of the wireless power transmission circuit using the current sensor while outputting the first power, in a first state where the external device is not in proximity, identify a phase delay value between the first phase of the first current and a second phase of a second current, and identify a second state where the external device is in proximity when the identified phase delay value is equal to or greater than a designated threshold.
