One time I disconnected the Apple Watch charger and the magnetic attachment landed right next to an external hard drive. Since the charger uses magnetic field to charge the Apple Watch, will placing it a few inches or right next to an external hard drive on the desk cause possible data loss to the hard drive? Or what if it is a wallet with credit cards in it. There are some possible scenarios:

1. a few inches next to it
2. right next to it
3. while charging, especially if it is 8 or 10 hours
4. when just within the few seconds disconnected from the Apple Watch
5. when not attached to the Apple Watch
