Apple has issued a warning that the magnets inside iPhone 12 can interfere with medical devices.
A study conducted by the cardiologists led by Dr. Gurjit Singh at the Henry Ford Medical Center found that the new iPhone 12 affected the safe operation of cardiac support devices. The iPhone has a circular array of magnets that makes the phone compatible with MagSafe accessories. But the magnet inside the iPhone can change how the cardiac support devices function and cause the heart to beat out of sync. The study was published in the medical journal HeartRhythm.
Apple also issued a warning on its website. The new iPhone 12 device contains magnets and components and radios that emit electromagnetic fields, interfering with the pacemakers and other medical devices. The sensors in the cardiac devices respond to the magnets and radios when in close contact with iPhone 12 and its accessories, resulting in deactivation. Apple said that iPhone 12 models contain more magnets and are susceptible to cause magnetic interference when compared with the previous versions of the iPhone. It advised maintaining a safe distance to avoid any potential interactions with the devices.
