A charger for attachment to a mobile device. A housing with a device side surface contains a wireless charger including at least one coil. A first arrangement of magnetic material has a first region exposing a first polarity magnetic field at the device side surface and a second immediately adjacent region exposing an opposite polarity magnetic field at the device side surface. In use, the arrangement magnetically couples the housing to a mobile device and causes the housing to adopt a specific axial orientation on the mobile device thereby assuring substantial axial alignment of the at least one coil with a corresponding coil associated with the mobile device.
