Abstract
An accessory to device coupling system can include a first magnet array adapted for assembly with respect to a surface of an electronic device and a second magnet array adapted for assembly with respect to a surface of an accessory device, the accessory device configured to interact electrically with the electronic device. The first magnet array can include a first plurality of magnets arranged in a first pattern of alternating polarities, and the second magnet array can include a second plurality of magnets arranged in a second pattern of alternating polarities that corresponds to the first pattern of alternating polarities. The corresponding alternating polarity patterns can cause the second magnet array to couple to the first magnet array with a normalized attraction force only at an intended orientation and alignment, and with less than half of the normalized attraction force at any other orientation and alignment.
