magnetic charger keep change magnetic field direction
Hi,
I bought the apple watch 3 couple of weeks ago, and charge it everyday with the genuine magnetic charger within the package.
However, I noticed that the direction of the charger seems flipping everyday.
The first time I charged the watch, the back of the watch was contacted with the curved side of the charger when aligned, which seems correct.
But sometimes when I charged it, I have to use the back side (flat side) to contact with the back of the watch to get the proper alignment, i.e. the charger attracts the watch, instead of repelling it.
From the observation, the magnetic field direction (or magnet polarity) reverses every day. Within the same day, no matter how many times I attach or detach the watch from the charger, the polarity seems remaining.
May I know whether this is a normal situation, i.e. the charger is designed to be like this, or it is something wrong?
Thanks.
Apple Watch Series 3
