Zusammenfassung:	Disclosed is a method and apparatus for determining mutual inductance for effective wireless power transmission. The apparatus includes a resonance circuit unit including at least one transmission resonance circuit and at least one reception resonance circuit and configured to transmit power to the reception resonance circuit using power supplied to the transmission resonance circuit, and a controller configured to determine a mutual inductance value related to a transmission resonance circuit to which power is supplied when power is supplied only to any one transmission resonance circuit of the at least one transmission resonance circuit and power supply to another transmission resonance circuit is blocked, and to determine a sign of mutual inductance related to a transmission resonance circuit to which power is supplied when power is supplied only to a reference transmission resonance circuit and any one transmission resonance circuit except for the reference transmission resonance circuit.
