From speakers, receivers, vibration mode motors, head feedback motors, to voice coil motors in camera autofocus mechanisms, magnets have become an indispensable part of consumer electronics. And Apple’s high-end smart mobile devices have taken advantage of neodymium magnets to create their own unique product ecosystem.
Whether it’s an iPhone, iPad, or MacBook, they all have many tiny NdFeB magnets inside their bodies. The iPad Pro, for example, contains as many as 102 magnets in order to better adapt to other products. This also accidentally makes the tablet computer can be directly used as a refrigerator magnet. These magnets in iPad Pro have four functions, namely wake-up function, magnetic attraction, magnetic fixing and magnetic connection.
