A wireless power transmission apparatus includes a resonance unit including resonators and configured to form a magnetic resonant coupling with another resonator, and a feeding unit configured to transmit alternating current (AC) power to one of the resonators. The wireless power transmission apparatus further includes a controller configured to determine a value of a capacitor connected to one of the resonators, based on a magnitude of a magnetic field formed by the resonance unit.
