What are magnetic devices

Information about the magnets in the iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max and MagSafe accessories

The iPhone contains magnets as well as components and radio units that emit electromagnetic fields. All MagSafe accessories (each sold separately) also contain magnets - and MagSafe chargers and MagSafe Duo chargers contain radio units. Under certain circumstances, these magnets and electromagnetic fields can impair the function of medical devices.

While all iPhone 12 models contain more magnets than previous iPhone models, they are not expected to present a greater risk of magnetic interference with medical devices than previous iPhone models.

Medical devices such as implanted pacemakers and defibrillators can contain sensors that react to magnets and radio units when in close contact. To avoid possible interactions with these devices, keep your iPhone and MagSafe accessories a safe distance from your device (more than 15 cm or more than 30 cm if you are charging wirelessly). Either way, check with your doctor and device manufacturer for specific guidelines.

Manufacturers often make recommendations for safe use your devices near wireless or magnetic products to avoid possible interference. If you think the iPhone or MagSafe accessory is interfering with your medical device, stop using your iPhone or MagSafe accessory.
