    80mm Disc Neodymium Magnets

    Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet, and when handling due to their brittle nature and to avoid injury due to pinching.


    What is the largest neodymium magnet?

    The largest neodymium magnet currently available commercially is typically in the form of a block or disc magnet, with dimensions ranging from a few inches to several inches in length and width. These larger neodymium magnets can have significant magnetic pulling force and are used in various applications such as industrial equipment, magnetic separators, motors, and generators.While there is no definitive size limit for neodymium magnets, it's important to note that as the size increases, the magnet's magnetic strength may decrease. This is because larger magnets may have a higher likelihood of internal magnetic domains canceling each other out, reducing their overall magnetic field strength. However, advancements in magnet manufacturing techniques have allowed for the production of larger neodymium magnets with improved magnetic properties.

    What are the strongest neodymium magnets in the world?

    The strongest neodymium magnets commercially available are known as "super magnets." Among super magnets, the "N52" grade is currently the strongest commonly used grade. N52 magnets have a maximum energy product (BHmax) of approximately 52 Mega-Gauss-Oersteds (MGOe). These magnets offer exceptionally strong magnetic fields and high magnetic strength, making them suitable for various applications where powerful attraction or repulsion forces are required.It's worth noting that while the N52 grade is the strongest readily available option, there are experimental or special production magnets that have achieved even higher magnetic properties. 

    Is neodymium harmful to humans?

    Neodymium itself is not inherently harmful to humans. It is a rare earth element that is generally considered to be safe when it is in its pure form. However, it's important to note that neodymium magnets, which are made from a combination of neodymium, iron, and boron, can be very powerful and pose potential risks if mishandled.If neodymium magnets are swallowed, they can cause serious injury or even death, as they can attract to each other or to metal objects within the body, leading to blockages or perforations in the digestive system. Therefore, it is essential to keep neodymium magnets out of the reach of children and to exercise caution when handling them.Additionally, neodymium magnets can produce strong magnetic fields, so individuals with pacemakers or other electronic medical devices should avoid close contact with these magnets as they can interfere with the function of these devices.Overall, while neodymium itself is not toxic, it is important to handle neodymium magnets with care, follow safety guidelines, and seek appropriate medical attention if accidents or ingestion occur.

    What are 5 common uses of neodymium?
    1. Neodymium magnets: The most common and widely recognized use of neodymium is in the production of powerful permanent magnets. These magnets are used in various applications, including electric motors, speakers, headphones, hard disk drives, and magnetic fasteners.
    2. Wind turbines: Neodymium-based magnets are key components in the generators of modern wind turbines. The magnets help in converting the mechanical energy of the wind into electrical energy.
    3. Electric vehicles: Neodymium magnets are essential in electric vehicle motors. The high strength and magnetic properties of neodymium make it well-suited for generating the required power and efficiency in electric motors.
    4. Audio systems: Neodymium magnets are used in high-quality audio systems such as headphones and speakers. Their small size and strong magnetic field allow for compact designs without compromising sound quality.
    5. Medical imaging: Neodymium is used in the production of contrast agents for magnetic resonance imaging (MRI). These agents help enhance the visibility of specific tissues and organs during medical imaging procedures.
