According to one embodiment, an electronic device includes a housing, a touch panel in the housing, a power transmitter in the housing, and an active stylus. The active stylus is capable of receiving power wirelessly from the power transmitter. The power transmitter includes a first coil to generate magnetic flux orthogonal to an upper surface of the housing for transmitting power. The active stylus includes one or more second coils for receiving power to resonate with the magnetic flux, at least one of the one or more second coils configured to be parallel to the first coil when the active stylus is in a first position or in a second position on the upper surface of the housing. |
