1. An electronic device comprising:
a housing;
a memory;
a first electrode and a second electrode disposed in the housing;
a charging circuit configured to receive power from an external charging device;
a first touch sensor;
a magnetic sensor;
a first switch; and
a processor electrically connected to the memory, the charging circuit, the first touch sensor, the magnetic sensor, and the first switch,
wherein the memory stores instructions that, when executed, cause the processor to:
sense a numerical value of a magnetic flux of a magnetic material contained in the external charging device via the magnetic sensor; and
control the first switch to selectively connect the first electrode and the first touch sensor or the charging circuit to each other based on the numerical value of the magnetic flux,
wherein when executed, the instructions cause the processor to:
control the first switch to connect the first touch sensor and the first electrode to each other when the numerical value of the magnetic flux is smaller than a specified first magnetic flux;
sense a first capacitance of the first electrode via the first touch sensor; and
determine whether a user is wearing the electronic device based on the first capacitance.
