Computer Magnets

Computer magnets are fundamental components in modern technology, silently powering the digital world. With their ability to generate strong magnetic fields, computer magnets have revolutionised data storage and processing, making them essential for the functionality of the digital age's most prevalent tools and devices. Learn more about how magnets are used in the computing industry and how Bunting can deliver first-class products.

Magnetic challenges in computer applications

Magnetic challenges in computer applications primarily revolve around ensuring reliable data storage, processing and overall device performance.

But one major challenge is miniaturisation. Today, technological devices are getting smaller and smaller but still require equally powerful magnets. Manufacturers like Bunting are dedicated to solving these challenges, collaborating with universities to research magnetic fields and experiment with new magnets.

Magnets also carry a somewhat negative reputation when it comes to computers. It's a common belief that magnets have the potential to erase data from our hard drives, cause disruptions in computer monitors, or interfere with the electron flow within cables. So, maintaining data integrity in high-density storage while mitigating the risk of data loss is another hurdle.

Similarly, magnetic fields from surrounding devices or environmental factors can also disrupt sensitive components, demanding effective shielding and isolation techniques from today's magnet manufacturers.

Finally, balancing the need for powerful magnets with energy efficiency remains an ongoing challenge in designing magnetic systems for energy-conscious computing devices.

How magnets are used in computers

Permanent magnets are the most popular type of magnet used in modern computers, found in hard drives, floppy disks and CD drive heads. Approximately 4,000 tons of neodymium magnets (NdFeB) are annually used in computer drives, making up nearly 50% of total neodymium magnet sales.

These magnets are the most advanced commercialised permanent magnet materials used today, offering various grades that cater to multiple uses within the computing industry. However, thanks to their small size but impressive magnetic field, these magnets have found extensive use in computers. Most notably, they can be found in:

• Data storage
• Speakers and headphones
• Position sensors
• Motors
• Electromagnetic interference (EMI) shielding
• Magnetic disk drives
• Touchscreens
• Power supplies
• Printers
• Security systems
