A coaxial inductive power transfer and distribution apparatus includes a stationary primary conductor and a mobile secondary coil magnetically coupled together to provide for inductive power transfer therebetween. A return conductor that is stationary is mechanically coupled to the primary conductor and ensures the position stability of the primary conductor with respect to the moveable secondary coil. The return conductor also includes an air gap in which a support member for the mobile secondary coil is disposed within. The mobile secondary winding includes a high permeability toroidal core that is coaxially disposed about, and spaced apart from, the primary conductor. A multi-turn coil is radially disposed about the high permeability toroidal core. The support member for the mobile secondary winding extends through the air gap in the return conductor to the exterior of the return conductor, where it may be coupled to an electric vehicle.
