Apple has named the charger for the iPhone 12 and iPhone 12 Pro the MagSafe.
It looks like a sack that encloses with a drawstring.
What’s in MagSafe? I had an X-ray of MagSafe to find out how it was positioned.
I found a charging coil. A magnetic circle is placed around it.
A white rubber band was glued to the cover with a strong adhesive. I turned it upside down from the edges of the rubber sheet.
Under the white cover, a small piece of copper wire is placed around the coil. Below the coil is a small circuit board.
The structure is simple. When charging your phone, the charger is electrically charged, so you do not need a charger.
The charger needs to be plugged in.
