Also known merely as a neo magnet, a neodymium magnet is a type of uncommon-earth magnet that’s comprised of neodymium, iron and boron. Though there are other rare-earth magnets — together with samarium cobalt — neodymium is by far essentially the most common. They create a stronger magnetic subject, allowing for a superior stage of performance. Even if you’ve heard of neodymium magnets, though, there are probably some things you don’t know about these fashionable rare-earth magnets.

Overview of Neodymium Magnets
Dubbed the world’s strongest permanent magnet, neodymium magnets are magnets made of neodymium. To place their strength into perspective, they will produce magnetic fields with up to 1.4 teslas. Neodymium, in fact, is a uncommon-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 were invented in the early Eighties by Common Motors and Sumitomo Special Metals. The businesses discovered that by combining neodymium with small quantities of iron and boron, they had been able to produce a robust magnet. Basic Motors and Sumitomo Particular Metals then launched the world’s first neodymium magnets, offering a cheap alternative to different rare-earth magnets on the market.

Neodymium vs Ceramic Magnets
How do neodymium magnets compare to ceramic magnets precisely? Ceramic magnets are undoubtedly cheaper, making them a well-liked choice for consumer applications. For commercial applications, nonetheless, there’s no substitution for neodymium magnets. As beforehand talked about, neodymium magnets can create magnetic fields with as much as 1.4 teslas. In comparison, ceramic magnets usually 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 prone to damage. If you drop a ceramic magnet on the ground, there’s a great probability it should break. Neodymium magnets, on the other hand, are physically harder, so they're less prone to break when dropped or otherwise uncovered to stress.

Alternatively, ceramic magnets are more resistant to corrosion than neodymium magnets. Even when exposed to humidity frequently, ceramic magnets generally won’t corrode or rust.
