Neodymium NdFeB disc magnets are the common shapes of magnets, their shape can be edited and designed with different thicknesses and diameters to increase the surface area of the poles, which therefore increases the magnet's pull strength. Due to their wide & flat surface, disc magnets have a large pole area to make them strong and effective. Depending on the size of the disc, it has multiple uses, such as being used in packaging boxes, handbags, personal experiments, electronic products, smart homes, acoustic areas, etc.

READ MORENdFeB is a high-performance permanent magnet material made of an alloy of the rare earth elements neodymium (Nd), iron (Fe), and boron (B).
It is hailed as the "King of Magnets" because it is currently the strongest commercially available permanent magnet with the highest magnetic energy product.
The NdFeB material itself endows the magnet with an extremely high magnetic energy product, while the disc shape maximizes its performance.
The magnetization of a disc magnet is typically along its axial direction (thickness direction), with the two large planes of the disc serving as the N and S poles.
This design significantly increases the surface area of the magnetic poles. According to magnetic field theory, the larger the area of the magnetic poles, the more concentrated the magnetic field lines are within a certain distance, thus resulting in stronger effective attraction and holding forces at the contact surface.
The disc shape is easy to manufacture and standardize, making it ideal for embedding into various product structures, especially in applications requiring flat or concealed installation, such as packaging boxes and hidden snap-fit fasteners in smart home devices.
NdFeB disc magnets, with their strong magnetic force and versatile sizes, play an indispensable role in many high-tech and traditional industries. Their core value lies in providing a stable, reliable, and strong magnetic field to meet the needs of different fields for high-performance permanent magnets.
Typical Applications: Vibration motors in mobile phones, speaker transducers inside headphones, and voice coil motors in computer hard disk drives (HDDs).
Core Requirements: Generating a high-intensity magnetic field within extremely limited space to ensure efficient operation of micro-motors and superior sound quality in acoustic products. Miniature disc magnets are a key component for achieving product thinness and high performance.
Typical Applications: Drive motors in new energy vehicles, servo motors in industrial automation, and generator cores in large clean energy equipment (such as wind turbines).
Core Requirements: As high-efficiency motor magnets or permanent magnet motor disks, they provide constant magnetic force to generate powerful torque and energy conversion efficiency, serving as the power source for modern high-efficiency motor systems.
Typical Applications: Precision magnetic field construction in MRI equipment, small implantable or external medical pumps, and various magnetic therapy products.
Core Requirements: Precision medical magnets require extremely high magnetic field uniformity and stability to ensure accuracy in diagnosis and treatment. NdFeB disk magnets are widely used due to their controllable magnetic field distribution.
Typical Applications: Magnetic clasps for high-end packaging boxes and handbags, magnetic adsorption tools for quick fixation, office supplies, and DIY models and sensor switches.
Core requirement: Relying on its strong magnetic attraction properties, it enables quick connection, reliable fixation, or contactless sensing of items, greatly enhancing the user experience and functionality of the product.
