Extreme care must be excercised when handling neodymium magnets as they can easily pinch fingers. All neodymium magnets oxidize fairly rapidly when exposed, so an anti-corrosive coating (usually electroplating) is used to extend their useful lifespan. Various grades of neodymium magnets are available with varying temperature and MGO characteristics. Includes 10 rings, stacking post and challenge booklet. DETAILS: Ideal for boys & girls ages 3 years & up. Magnetic Match Rings is the fun way to learn about magnetism, help develop visual matching skills, and improve eye-hand coordination. 2022 Popular Neodymium Magnet Ring Magnetic Fidget Fingers Magnetic Rings. These rings come in a pack of 3 and are a great alternative to the fidget spinner, put your finger through one or more of the rings and spin your fingers. FUN STEM TOYS: Encourage curiosity and learning through play. Neodymium magnets (sintered NdFeB) are more powerful than any other permanent magnet material on the market today. Explore our finger magnet rings in different sizes, including pocket and. Neodymium magnetshave a somewhat lower maximum operating temperature than other types of magnetic materials, so this should be considered when choosing a grade. Their max energy product can be 35MGOe~50MGOe, Neodymium magnets are developed rapidly and applied widely due to their perfect characteristic, rich raw material resource and reasonable price. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. Our sister company, Integrated Magnetics, has over 60 years of experience in manufacturing complex magnetic assemblies for more technical applications.Rings neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals in rings sharps. We can custom manufacturer neodymium ring magnets to fit your exact specifications, just send us a special request and we’ll help you determine the most cost effective solution for your specialty project. Visit our applications page to learn more. NdFeB rod and cylinder magnets are often used in power generation equipment, high performance motors, consumer electronics, magnetic sensors, high-end audio equipment, surgical instruments and high-intensity separators for industrial, medical, aerospace, automotive and commercial industries as well as consumer use. Standard tolerances are +/- 0.005” on both diameter and thickness dimensions. Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings. Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure. Please be sure to test the actual pull in your actual application. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2' thick mild steel plate. The approximate pull info listed is for reference only. * $15.00 total minimum order (excluding shipping & tax if applicable) - Items can be combined to reach the minimum amount. Not all of our magnets are shown on this website so please contact us today if you don’t see what you are looking for. Finishing options for NdFeB ring magnets are uncoated, with a triple- coating (Ni-Cu-Ni) nickel finish or coated with Aluminum IVD (Ion Vapor Deposition) for optimal corrosion resistance. We stock licensed neodymium ring magnets in different lengths, OD/ ID diameters, finishes and premium grades. Neodymium Ring Magnets in Assorted Sizes and Shapes

Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to make a design smaller while achieving the same result. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials.

Neodymium ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center.
