I thought that coil was the NFC coil so that the phone could identify the case and accessories. It’s only a few threads, which would be small for an induction coil.
Oh, I see. No, apparently, Apple guards its NFC protocols extremely closely. Only recently have they been (forced to be) more open about how it all works— and to allow third-party access.
The magnet and the charging coil aren’t the same afaik. They’re located together since their functionality is linked, but ultimately they are separate.
It’s a conduction ring, too, so that the charge gets from the charger to the phone.
But people who don’t know should be made aware of this that iPhone cases now also contain magnets.

Yeah, the more I look up this, it looks like an NFC loop is part of the MagSafe / Qi 2 protocols.
