摘要： An inductive power transfer apparatus (1) may be used for producing or receiving a magnetic field for inductive power transfer. The apparatus has a central coil (5) and two end coils (3,4), one of the end coils being provided at each end of the central coil (5). Some turns of each of the end coils (3,4) are on one side of the central coil (5) and the remaining turns are on the other side. The end coils act to weaken or cancel flux on one side of the central coil (5) and guide magnetic flux through the central coil to provide an arch shaped flux pattern beyond the apparatus on the other side of the central coil.
