What Are Neodymium Magnets

Also known merely as a neo magnet, a neodymium magnet is a type of rare-earth magnet that’s comprised of neodymium, iron and boron. Although there are different rare-earth magnets — including samarium cobalt — neodymium is by far essentially the most common. They create a stronger magnetic area, permitting for a superior degree of performance. Even for those who’ve heard of neodymium magnets, though, there are probably some things you don’t learn about these standard uncommon-earth magnets.

Overview of Neodymium Magnets
Dubbed the world’s strongest everlasting magnet, neodymium magnets are magnets made of neodymium. To place their energy into perspective, they will produce magnetic fields with up to 1.four teslas. Neodymium, of course, is a rare-earth component that includes the atomic number 60. It was discovered in 1885 by chemist Carl Auer von Welsbach. With that said, it wasn’t until practically a century later till neodymium magnets had been invented.

History of Neodymium Magnets
Neodymium magnets have been invented in the early Eighties by General Motors and Sumitomo Particular Metals. The companies discovered that by combining neodymium with small amounts of iron and boron, they had been able to produce a strong magnet. General Motors and Sumitomo Special Metals then launched the world’s first neodymium magnets, offering an economical various to other rare-earth magnets on the market.

Neodymium vs Ceramic Magnets
How do neodymium magnets evaluate to ceramic magnets precisely? Ceramic magnets are undoubtedly cheaper, making them a well-liked selection for client applications. For commercial applications, nonetheless, there’s no substitution for neodymium magnets. As previously mentioned, neodymium magnets can create magnetic fields with up to 1.four teslas. Compared, ceramic magnets generally produce magnetic fields with just 0.5 to 1 teslas.

Not only are neodymium magnets stronger, magnetically, than ceramic magnets; they're harder as well. Ceramic magnets are brittle, making them inclined to damage. If you happen to drop a ceramic magnet on the ground, there’s a good probability it'll break. Neodymium magnets, then again, are physically harder, so they're less more likely to break when dropped or otherwise uncovered to stress.

Alternatively, ceramic magnets are more immune to corrosion than neodymium magnets. Even when exposed to humidity regularly, ceramic magnets usually won’t corrode or rust.
