After the release of the iPhone 12 series in June last year, Apple admitted that these devices supporting MagSafe magnetic attraction technology would cause interference to medical equipment.
Now, Apple has updated official website's technical support documents and sent important security reminders to iPhone 12 users.
1On October 23rd, Apple 65438+ updated the technical support document of "Magnets in iPhone 12 and MagSafe Magnetic Accessories Series" in official website.
Apple said that the iPhone contains magnets, as well as components and radios that emit electromagnetic fields, and all MagSafe magnetic accessories (each sold separately) also contain magnets.
Moreover, both MagSafe charger and MagSafe dual charger contain radio equipment, and these magnets and electromagnetic fields may cause interference to medical equipment.
Medical devices such as implantable pacemakers and defibrillators may contain sensors that respond to magnets and radios when in close contact.
To avoid any potential interaction with these medical devices, please keep your iPhone and MagSafe magnetic accessories at a safe distance from your medical devices. Please consult your doctor and equipment manufacturer for specific guidelines.
In the "Important Safety Information of iPhone", Apple also said that the magnets contained in the iPhone, as well as some components and radio equipment, will emit electromagnetic fields.
These magnets and electromagnetic fields may interfere with medical equipment, such as cochlear implants, hearing AIDS, pacemakers, defibrillators or other medical equipment.
If you suspect that iPhone is interfering with your medical equipment, please stop using iPhone.
Apple also stressed that although all iPhone 12 models contain more magnets than previous iPhone models, it is expected that the risk of electromagnetic interference to medical equipment will not be higher than that of previous iPhone models.
According to 9to5mac, a study in Heart Rate Journal found that the MagSafe technology of iPhone 12 can disable pacemakers in some cases.
Similarly, the problem lies in the magnet itself, not necessarily iPhone 12. Any magnet with a certain strength will have an impact on the pacemaker.
