Could you probe the magnet ring with a small magnet to see if the polarity alternates?
We’d love to know the dimensions of the magnet array on the phone. What is the inside diameter? What is the outside diameter? What is the length of the line of magnets? What distance from the center of the magnet ring does the line of magnets start and stop?
Concerning the charger itself…. What is the inside diameter of the ring? What is the outside diameter of the ring?
It would be great if you had a precise scale reference in a straight-on photo of the magnet array in the phone.
Thanks for your work!
