80mm Disc Neodymium Magnets – Custom Magnet Manufacturer | Fullzen

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.

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. 

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.
