Original Abstract Submitted
A device or an accessory may include a near-field communications antenna and a soft magnetic ring concentric with the near-field communications antenna. The device or accessory may further include at least one wireless power transfer coil concentric with the near-field communications antenna, a rectifier coupled to the at least one wireless power transfer coil, and a battery configured to receive a rectified voltage from the rectifier. The soft magnetic ring may be used to shunt magnetic flux from one or more nearby magnets in external electronic devices to prevent the magnets from repelling each other. The soft magnetic ring may be attracted to a magnet in an external device to help align wireless power transfer coils in the two mated devices.
