An article in the Heart Rhythm magazine revealed that Apple’s iPhone 12 and MagSafe-approved accessories could interfere with medical devices. Apple acknowledged the problem and released a statement sharing information on the issue.
The article in Heart Rhythm magazine, dated January 4, 2021, claimed that the new magnets in the iPhone 12, part of MagSafe technology, could interfere with medically implanted devices such as pacemakers. This could potentially lead to problems as these devices use precision sensors and electromagnets.
Medical devices such as implanted pacemakers and defibrillators may contain sensors that respond to magnets and radios when in close contact. To avoid any potential interaction with these devices, take care to keep your iPhone and MagSafe accessories at a safe distance, ie more than 30 cm from your device. However, for special cases, you need to consult your doctor and device manufacturer.
Also, All MagSafe accessories contain magnets and include the Charger and Duo Charger radio. These magnets and electromagnetic fields can interfere with medical equipment.
Apple argues that although the iPhone 12 has more magnets than previous iPhone models, it does not pose a greater risk of magnetic interference in medical devices.
