A system for inductive charging is provided. In accordance with an embodiment, the system comprises a permanent magnet structure having two or more discontinuous permanent magnet sections assembled to form a full or partial ring shape. The sections are each magnetized in a direction perpendicular to their top and bottom surfaces in a pattern comprising multiple opposing poles at each surface to reduce an effect of a magnetic field generated by the permanent magnet structure on magnetically sensitive components of the portable device or battery or other nearby devices.
