Project Description

Neodymium magnets play a crucial role in modern electronics. We can’t see them with the naked eye, but they work silently inside various device, providing a wide range of functionalities and enhancing the user experience.

Take the mobile phones we use every day as an example, they contain many small neodymium magnets with the following functions:

  • VIBRATOR MAGNETS: Vibrators (vibration motors) in smartphones often contain magnetic elements. These magnets generate vibrations in the vibrator, enabling functions such as incoming call and message reminders.
  • MAGNETIC INDUCTION CHARGING MAGNET: Some mobile phones support magnetic induction wireless charging, in which there may be a magnetic element on the back of the mobile phone to attract and wirelessly charge the corresponding magnetic induction charger.

  • MAGNETIC SENSORS: Some smartphones have built-in magnetic sensors such as electronic compasses and magnetic field sensors. The electronic compass is used to determine the direction and positioning of the mobile phone, while the magnetic field sensor is used to detect changes in the magnetic field around the mobile phone. These sensors play an important role in navigation, compass functionality, screen rotation, and more.
  • MAGNETIC PHONE CASES AND ACCESSORIES: Some phone cases and accessories are magnetically designed to attach to the phone with magnets, providing extra protection and keeping the phone stable on a magnetic mount for viewing content or navigating, etc.

These small rare earth magnets are often carefully designed and placed to ensure that their interactions do not negatively affect each other. And phone manufacturers test and verify these designs. They will ensure that the performance and functionality of the phone will not be interfered by these small but powerful magnets.


Magnets have gained popularity in phones, personal electronics, and accessories for several reasons due to their unique and versatile properties. Here are the key factors that contribute to their widespread use:

  • COMPACT SIZE: Magnets can be made in various shapes and sizes, allowing for easy integration into small and slim electronic devices without adding significant bulk or weight.
  • EASE OF USE: The magnetic force enables quick and effortless connections and attachments between different components and accessories, enhancing user convenience and interaction.
  • SECURE MOUNTING: Magnets provide a reliable and secure method for mounting devices and accessories. They prevent accidental detachment and ensure that components stay in place during regular use, reducing the risk of damage from falls or impacts.
  • REDUCED WEAR AND TEAR: Unlike mechanical connectors, magnets do not experience wear and tear from frequent usage, making them more durable and long-lasting.
  • WIRELESS CHARGING: Magnets facilitate wireless charging by enabling efficient energy transfer between devices and charging pads. This feature eliminates the need for physical connectors and simplifies the charging process.
  • FLEXIBILITY IN DESIGN: Magnets offer design flexibility, allowing manufacturers to create innovative and space-efficient products. They enable the development of modular devices and accessories that can be easily attached, detached, and customized by users.
  • SENSOR CAPABILITIES: Magnetic sensors, such as compasses, are essential for various applications in smartphones and other devices. They provide accurate orientation and navigation information, enhancing user experience and enabling location-based services.
  • MINIMAL INTERFERENCE: Magnets used in electronic devices are designed to have minimal interference with other components, ensuring the smooth functioning of the overall device.
  • AESTHETIC APPEAL: Magnets can be concealed within the device’s structure, resulting in a clean and aesthetically pleasing design without visible connectors or attachment mechanisms.
  • COST-EFFECTIVENESS: Magnets are relatively cost-effective to produce and incorporate into electronic devices and accessories, making them a viable option for manufacturers looking to offer attractive features without significantly increasing production costs.
  • VERSATILITY: Magnets find applications in various electronic devices, from smartphones and tablets to smartwatches, headphones, and even larger electronic accessories like car mounts.
  • ENHANCED USER EXPERIENCE: The use of magnets in devices and accessories simplifies tasks such as mounting, charging, and organizing cables, enhancing the overall user experience and convenience.


Apple has always paid attention to product design and user experience, and the small magnets have played a key role in this. And they have created its own unique ecosystem of products using these small neodymium magnets. Whether iPhone, iPad, or MacBook, they all have many tiny NdFeB magnets inside their bodies.

The iPad Pro, for example, even 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.

Here are some more examples of small magnets used in Apple products and what they do:

Tiny Strong Neodymium Magnets in AirPods

Apple uses MagSafe charging technology in its new iPhones and MacBooks. This technology uses small magnets to attach the charger to the device, ensuring that the charger is properly aligned and firmly attached to the device. This helps to increase the efficiency and convenience of charging, and reduces damage caused by incorrectly plugging in the charging cable.


Apple’s iPad Smart Cover and Smart Keyboard accessories also use magnets. These accessories can be attached to the iPad with magnets, providing protection and kickstand functions for the device. When the Smart Cover is opened or closed, the iPad automatically turns on or goes to sleep, thanks to the sensing action of the magnets.


Apple has launched a series of MagSafe accessories, such as MagSafe phone cases, MagSafe wallets, and more. These accessories use small magnets to securely attach to the iPhone, ensuring its stability and providing additional functionality.


Apple’s smart speaker, the HomePod, uses a magnetic base on the bottom. This magnetic mount securely attaches HomePod to flat surfaces and prevents it from being accidentally knocked over or slipped.


The AirPods charging box has built-in small magnets so that the AirPods can be safely and securely stored in the charging box to avoid accidental drop or loss. Magnets also ensure correct charging connection and automatic pairing.


The Apple Pencil is firmly attached to the iPad Pro with a built-in magnet, realizing automatic pairing and charging functions without complicated operations. Plus, it conveniently attaches to the side of your iPad Pro or a supported Apple Pencil accessory for easy portability and storage.

As we all know, Apple has always focused on the consistency and user experience of their product ecosystem. By using small magnets and MagSafe technology, accessories for Apple devices can be attached and detached more easily, while providing more functionality and convenience. This results in a better experience for users and tighter integration between Apple products and makes Apple products unique in the market too.


Small strong magnets allow Apple to avoid destroying the integrity of the product’s appearance. At the same time, it eliminates unnecessary lock structures for many of its products, making the products truly simple and consistent. For most users, they may not even notice the presence of permanent magnets when they connect products and accessories. These strong small magnets work quietly inside the phone case. The invisible maintenance is obviously the greatest value of small strong neodymium magnets for Apple devices.

The unique charm of magnetic design makes small rare earth magnets one of the favorite materials for product designers. Tiny strong NdFeB magnets are increasingly being used in novelty items.
