Never put the iPhone 12 in a shirt pocket if you have a pacemaker, MagSafe study finds

It looks like Apple wasn't extra cautious when it warned in the iPhone 12's new MagSafe charging system could affect not only magnetic stripe cards and RFID tags, but also "interfere with medical devices" like pacemakers and defibrillators. Why?

Not only does the MagSafe coil underneath the iPhones 12 models' back plate contain magnets, but the MagSafe accessories do too, not to mention the MagSafe Charger and MagSafe Duo Charger that add electromagnetic fields to the equation. 


All of those could affect the operation of "medical devices," i.e. pacemakers, and a cardiologist from the Henry Ford Heart and Vascular Institute put Apple's warning labels to the test. Dr Singh checked how the MagSafe components are affecting the work of implantable defibrillators, and by and large found that the defibrillator safety switch detected the iPhone 12's magnets, and shut its functions down indeed:


That's the second study that shows a causal link that proves the iPhone 12's MagSafe interference with pacemakers and the like, and that is why Apple added a grand disclaimer regarding the safe MagSafe usage:
