How does Magsafe work?
MagSafe uses a ring of magnets in the iPhone 12 models to connect to accessories that also have built-in magnets. So, for example, Apple's MagSafe charger clips directly to the back of an iPhone , just like a magnet attaches to a refrigerator. The cases are the same way, they clip onto the magnetic ring built into the iPhone. The magnetic ring design allows the iPhone 12 models to be compatible with a whole range of accessories that rely on magnets, from chargers to mounts to cases. The iPhone 12 and iPhone 13 models have a ring of 18 rectangular magnets arranged in a circular shape located underneath the wireless charging coil in each device, which is what allows for the magic of MagSafe. Older iPhones had the same wireless charging coil, but no magnet underneath to allow for magnetic connections.

The MagSafe charger resembles a larger Apple Watch charging disc with an aluminum body and soft white material at the top of the charger. The charger clips onto an iPhone with magnets inside, perfectly aligning the charging coil in the MagSafe charger with the charging coil in the iPhone. The iFixit repair site took apart a MagSafe charger and took an X-ray to show us the internal design of the charger. As with the iPhone, inside there are a series of magnets compatible with the iPhone magnets that surround an internal charging coil and a circuit board that manages the charging process.
WARNINGS ABOUT MAGSAFE LOADER
When using the MagSafe charger, Apple warns that it can leave a footprint on leather cases designed for iPhone MagSafe, which you need to be aware of.
It can also leave a mark on silicone cases based on MacRumors reader reports, and it's possible that this may affect third-party cases made from soft materials as well.
Apple advises those who are concerned about the ring that MagSafe may be causing to choose the silicone or clear cases instead of the leather versions.
