    a resonator including a magnetic core and a coil wound around the magnetic core, the resonator wirelessly transmitting the AC power supplied from the power supply to a different resonator arranged to be opposed to the resonator;

    an adjuster to move magnetic core along a longitudinal direction of the coil; and

    a controller to control the adjuster based on a value of current flowing in the resonator to adjust relative positions of the magnetic core and the coil,wherein the magnetic core includes a plurality of magnetic blocks spaced apart from each other, andthe adjuster moves only a part of the magnetic blocks along the longitudinal direction of the coil.
