Why Is My Phone Magnetic? Where the Magnets Are and Why They’re There

If your phone snaps onto a fridge magnet or a car mount, nothing is wrong with it. Phones contain several magnets, and on most recent iPhones there’s a whole ring of them on purpose. Here’s where they are, what they do, and when magnetism in a phone is worth a second look.

The Short Answer

Your phone is magnetic because it contains permanent magnets and magnetic metal parts. The biggest source on most iPhone 12 and later models is the MagSafe magnet ring behind the back glass. Every phone also has small magnets in its speakers, earpiece and vibration motor, and some have steel parts that magnets attract.

1. The MagSafe Magnet Ring (Most iPhone 12 and Later)

Most iPhones since the iPhone 12 include a circle of magnets behind the back that holds chargers, wallets and mounts in place. Apple says the magnets ensure proper alignment for fast wireless charging. Budget models such as the iPhone SE and iPhone 16e don’t have MagSafe.

This ring is why a MagSafe iPhone sticks so strongly to the back of a magnetic car mount. See our picks for the best iPhone car mounts.

2. Qi2 Magnets in Some Android Phones

The Wireless Power Consortium describes Qi2 as a wireless charging standard with magnetic attachment for alignment. Some newer Android phones build the magnets in, while others are “Qi2 Ready” and need a magnetic case. If your Android phone sticks to a magnet near the center of the back, it may have built-in magnets, or your case may have them.

3. Speakers and the Earpiece

Phone speakers work by moving a tiny coil against a permanent magnet. Your phone has at least one loudspeaker and an earpiece speaker, so you may feel a weak pull near the top and bottom edges.

4. The Vibration Motor

The haptic motor that buzzes and taps uses magnets and coils too. It’s usually near the bottom of the phone.

5. Cameras and Sensors

Camera modules use small magnets and coils to move the lens for autofocus and optical image stabilization. Phones also contain a magnetometer (compass) that senses magnetic fields, and some use magnets with Hall-effect sensors to detect flip covers.

6. Your Case, Not Your Phone

If your phone only became magnetic after you put a case on, the case probably has a magnetic ring or a metal plate. Learn why in why do phone cases have magnets.

Is It Normal for a Phone to Be Magnetic?

Yes. Some pull near the speakers is normal on every phone, and a strong pull at the center of the back is normal on MagSafe iPhones and Qi2 phones. It doesn’t mean anything is damaged.

When to Pay Attention

• Medical devices: Apple notes that many medical device makers recommend keeping consumer electronics with magnets at least 6 inches (15 cm) from implanted devices like pacemakers, or 12 inches (30 cm) when wireless charging. Ask your doctor for guidance.
• Cards and key fobs: keep them out from between the phone and a MagSafe charger, per Apple’s MagSafe guidance.
• Compass errors: if a map points the wrong way while your phone sits on a magnetic mount, the mount’s magnet may be affecting the compass.
• A swollen or warped phone: this isn’t magnetism, but if the back bulges, the battery may be swelling. Stop using it and get it checked.

Frequently Asked Questions

The Bottom Line

Your phone is magnetic because it’s built with magnets: a MagSafe or Qi2 ring on many recent phones, plus speakers, the vibration motor and camera parts. It’s normal and harmless to the phone. Just keep it away from implanted medical devices and keep cards out from between the phone and a magnetic charger.
