Apple explains that 'MagSafe on iPhone 12 may interfere with the operation of medical devices such as pacemakers'

The back of iPhone 12 , iPhone 12 mini , iPhone 12 Pro , and iPhone 12 Pro Max has a built-in magnet for wireless charging called ' MagSafe ', which includes not only compatible chargers but also silicone cases and leather wallets. It is possible to attach the accessory to the iPhone body. However, it has been pointed out that the magnetic force and electromagnetic waves generated by MagSafe may affect medical devices such as pacemakers and defibrillators, and Apple has officially issued a statement.

In apaper published by doctors at Henry Ford Hospital in the United States in January 2021, the phenomenon that the ICD stopped working when the iPhone 12 with MagSafe was brought closer to the implantable cardioverter defibrillator (ICD) was reproduced. It has been reported. Doctors point out that if an ICD user puts the iPhone 12 in a chest pocket of clothing, the iPhone 12 'potentially interferes with the patient's life-saving therapy.'

Apple said, 'The iPhone uses magnets and components that emit electromagnetic waves, and wireless technology. MagSafe accessories also include magnets, and MagSafe chargers also use wireless technology. And electromagnetic waves can interfere with medical devices, 'he said, referring to MagSafe's impact on medical devices.

However, Apple said, 'All iPhone 12 models use more magnets than previous iPhones, but it is not expected to have a higher risk of magnetic interference with medical devices than previous iPhones. Hmm. '

On the other hand, 'Medical devices such as pacemakers and defibrillators may use sensors that react when approaching magnets or radios. Avoid affecting medical devices such as pacemakers and defibrillators. To do this, keep your iPhone and MagSafe accessories at a safe distance (15 cm or more, 30 cm or more when charging wirelessly) from your medical device, 'Apple announced.

Finally, Apple cautions, 'If you think your iPhone or MagSafe accessory is interfering with your medical device, stop using your iPhone or MagSafe accessory.'
