    Neodymium 25x3mm Magnet

    Neodymium magnets, also known as NdFeB magnets, are a type of rare-earth magnet made from an alloy of neodymium (Nd), iron (Fe), and boron (B). First developed in 1982 by General Motors and Sumitomo Special Metals, they have since become the strongest type of permanent magnet available on the market.

    • Discovery: The development of neodymium magnets was driven by the need for stronger, more efficient magnets to be used in electric motors, especially in the automotive industry.

     

    • Rare-Earth Magnets: Neodymium is part of the rare-earth elements, a group of 17 elements in the periodic table. Despite their name, rare-earth elements are relatively abundant, but they are challenging to mine and process.

     

    • Materials: Neodymium, iron, and boron combine to create an exceptionally strong magnetic field, much more powerful than traditional magnets like ferrite or alnico. The addition of small amounts of other elements (such as dysprosium or terbium) can improve the magnet's heat resistance and durability.

    We sell all grades of neodymium magnets, custom shapes, sizes, and coatings.

    Magnetic Product Description:

    This neodymium disc magnet size is 25x3mm Which the diameter is 25mm and the thickness is 3mm(N52 Nickel coating). This size magnet can reach around 6,500 to 7,500 Gauss and then pull force will be around 7-10 kg (15-22 lbs). 

    Uses For Our Strong 25x3mm Magnets:

    Consumer electronics: Used in devices such as smartphones, headphones, laptops, and hard drives, which require small but powerful magnets.

    Electric motors: Neodymium magnets are used in electric motors, especially in electric vehicles, drones, and other machinery that requires high efficiency.

    Medical devices: Essential in MRI machines and other medical technology due to their strong and stable magnetic fields.

    Renewable energy: Used in wind turbines and other forms of clean energy generation, where strong, lightweight magnets improve efficiency.

    Magnetic tools: Used in magnetic fasteners, couplings, sensors, and industrial automation systems.

     

    FAQ

    What is the maximum working temperature for your neodymium magnets?

    The maximum working temperature varies by magnet grade. For example, N35 to N52 magnets typically handle up to 80°C, while high-temperature magnets (such as the H series) can withstand temperatures between 120°C and 200°C. If you have high-temperature requirements, contact us for recommendations on suitable products.

    How are the magnets shipped? Is safety ensured during transportation?

    We package the magnets with magnetic shielding materials to ensure safe transportation and prevent interference with other goods or equipment during shipping. We also offer global shipping services and work with trusted logistics partners to ensure your magnets are delivered safely and on time.

    How can I prevent the magnets from demagnetizing in my application?

    Neodymium magnets are very resistant to demagnetization, but to avoid any risk, ensure the magnets are used within their specified temperature limits. Exceeding the maximum working temperature may cause a loss of magnetism. We also offer high-temperature resistant magnets, such as N45H or N52H, designed for demanding applications.
