Rare earth magnets are used in the mechanisms for image stabilization functions on digital cameras.

How does a smart phone use magnets?

A system called Pulse uses the magnetic field sensor, or magnetometer, for the compass app in iPhones and Android phones, to receive messages in the form of a varying magnetic field produced by a nearby electromagnet.

Can a magnet ruin a phone?

How can a magnet destroy a phone? The strong magnetic force from a magnet has the ability to get into a smartphone and interfere with the digital compass on the interior. Additionally, these magnetic fields can mess with the magnetometer and throw off the entire device.

Can magnets erase phone memory?

Can Magnets Wipe Phone Memory Off? It’s possible as long as the data stored in your smartphone’s memory was recorded magnetically. Magnets can corrupt outdated technology such as floppy hard drives, cassettes, credit cards and VHS.

How do magnets work in cell phones?

Evidence indicates that a magnet can affect the internal sensors of a smartphone, which operate on Hall Effect to give cardinal directions. The experimenters found out that bringing a magnet or a magnetic material closer to a smartphone causes a realignment of magnetic domains inside the phone and thus affecting the compass readings.
