MagSafe Magnet Strength

MagSafe implements a wound wire coil design that’s brand-new and cutting-edge in the industry. This coil is modified to work with magnets but still accommodates Qi wireless charging.The coil isn’t the only thing that makes MagSafe so amazing. In fact, the back of each MagSafe phone contains seven layers of components that are hard at work.

The internal charger contains multiple layers of shields, magnets and sensors that help facilitate charging and send your phone important information about accessories.

• Shields — The copper-graphite and nanocrystalline shields capture magnetic flux and allow the phone to safely charge at a faster rate without damaging the batteries or the electronics inside.
• Sensors — The sensors within the MagSafe component sense magnetic field strength and respond instantly, ensuring more responsive and efficient charging.
• Magnets — The magnets are what make the MagSafe so special. They allow you to precisely align your device for efficiency and let you connect cool extras securely without the need for clips, clamps or adhesives.
