An apparatus for determining a position between a wireless power transmitter and a wireless power receiver is provided. The apparatus comprises a first ferrite block having respective portions configured to be disposed in physical contact with each of adjacent second and third ferrite blocks separated by a first gap and with each of adjacent fourth and fifth ferrite blocks separated by a second gap. The apparatus further comprises a plurality of detection loops wrapped around the first ferrite block such that none of the plurality of detection loops physically contact the second, third, fourth or fifth ferrite blocks when the respective portions of the first ferrite block are in physical contact with the second, third, fourth or fifth ferrite blocks. Each of the plurality of detection loops are wrapped around the first ferrite block in mutually perpendicular planes from one another.
