Neodymium Magnets

Bunting Magnetics, through BuyMagnets.com, offers high quality Rare Earth Neodymium Magnets in Disc, Block, Ring and Countersunk Ring. Neodymium Magnets are super-strong permanent magnets – 10x stronger than the strongest ceramic magnet – and are available in stock and custom sizes. Neodymium Magnets are available for Standard temperature and High-temperature applications. Standard temperature Neodymium Magnets will begin to lose strength if they are heated above their maximum operating temperature, which is 180°F (80°C). High-temperature Neodymium Magnets can safely be used at operating temperatures up to 300° Fahrenheit (149° Celsius). Neodymium Magnets are a composition of Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, we recommend coating the magnet in nickel plating. Other coating options are zinc, tin, copper, epoxy, silver and gold. Rare Earth Magnets, such as Neodymium and Samarium Cobalt magnets, have a high resistance to demagnetization. Neodymium Magnets will not lose their magnetization around other magnets or if dropped. Neodymium Magnets will completely lose their magnetization if heated above their Curie temperature, which is 590°F (310°C) for standard N grades. BuyMagnets.com offers a selection of magnets that are of high-temperature material, which can withstand higher temperatures without losing strength. Neodymium Magnets have a variety of uses which include: Cell phones, loudspeakers, headphones, alternators, pacemakers, flow meters, linear actuators, gyroscopes, hybrid and electric vehicles, wind turbines, magnetic resonance imaging (MRI), motors in cordless tools, and magnetic guitar picks. Other applications are: Closers to hold a brochure, box or binder • Clamps to hold pieces of metal in place for welding, drilling, or machining • An oil filter as it filters metal chips out of oil • Stud Finders to locate a stud or find hidden nails and metal pieces inside walls. Neodymium Magnets must be handled with care to avoid injury and damage to you and the magnet. Fingers and hands can get severely pinched between two attracting magnets. Neodymium Magnets are brittle, and can peel, crack or shatter if allowed to slam together. Eye protection should be worn. Neodymium Magnets can also damage items such as credit cards, magnetic identification cards, or video tapes. Never place Neodymium Magnets near electronic devices. It is crucial to never allow Neodymium Magnets near a person with a pacemaker or similar medical aid. It is also important to keep Neodymium Magnets out of the reach of small children. Neodymium Magnets should not be machined. Neodymium material is brittle and prone to chipping and cracking, so it does not machine well by conventional methods. Machining the magnets will generate heat, which if not carefully controlled, can demagnetize the magnet or even ignite the material which is toxic when burned.
