Large Neodymium Disc Magnets – Custom Solutions | Fullzen
Large Diameter Disc Magnets (Upgraded to N52 from N42)
These large disc neodymium magnets with a slim profile have a relatively large surface area, which helps other objects stick to flat surfaces. The pulling force of such a magnet is distributed over a larger surface area, so its magnetic concentration is not as strong as that of a smaller but thicker neodymium magnet. It is also safer than 5mm or 10mm neodymium magnets of the same diameter. These rare earth neodymium magnets are exceptionally strong. They are made of NdFeB (Neodymium Iron Boron), which provides the highest usable magnetic energy of all materials. Large disc magnets are suitable for a variety of applications requiring very strong magnetic attraction. A nickel casing protects the magnets, as this material is very brittle.
We sell all grades of neodymium magnets, custom shapes, sizes, and coatings.
FAQ
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.
Neodymium disc magnets, also known as neodymium round magnets or neodymium cylinder magnets, are small cylindrical-shaped magnets made from neodymium-iron-boron (NdFeB) alloy. They are the most powerful permanent magnets commercially available.These magnets are often made in a disc shape, where the diameter is greater than the height (thickness), resulting in a flat circular shape. They come in various sizes, with diameters and thicknesses ranging from a few millimeters to several inches.Due to their high magnetic strength, neodymium disc magnets are widely used in a variety of applications, including electronics, medical devices, automotive industries, craft and hobby projects, magnetic closures, magnetic jewelry, and even in magnetic levitation experiments. Given their small size and strong magnetic field, they need to be handled with caution as they can attract or repel other magnetic objects and may cause injury if mishandled.
The "N" in neodymium refers to the chemical symbol of the element neodymium itself. Neodymium (Nd) is a rare-earth element that belongs to the lanthanide series of the periodic table. It is named after the Greek words "neos" meaning "new" and "didymos" meaning "twin," reflecting its discovery as a twin element to the previously known element, praseodymium.Neodymium is widely used in the production of strong permanent magnets, like neodymium magnets, due to its high magnetic properties. This element contributes to the strong magnetic field exhibited by neodymium magnets, making them sought-after in a variety of applications requiring a powerful magnetic force.
