About Neodymium Magnets

It all began rather quietly in 1984. Scientists working independently at General Motors and Sumitomo Special Metals discovered that when they combined the rare earth mineral neodymium together with iron and boron, they could create the world’s strongest permanent magnets: up to 10 times stronger than all other ceramic and alnico magnets available at that time.  Since then, neodymium magnets, also known as NdFeB magnets, have become a critical component in all types of modern electronic devices, from electric motors of all sizes to cellphones, computers, MRI scanners, wind turbines, electric vehicles, and more.   Neodymium Magnets in Cell Phones Cell...

Neodymium magnets work extremely well underwater. But there’s this cantankerous and inconvenient little catch. And it’s called corrosion.Neodymium magnets are typically plated with nickel to prevent rust and corrosion that results from moisture, but unless protected with a special corrosion-resistant coating, they are not waterproof.Nickel-coated neodymium magnets are usually referred to as indoor magnets. They should be kept away from water (especially salt water), as exposure to moisture can cause them to corrode and lose their magnetic strength over time. This is because neodymium magnets have a very high iron content of 64 to 68 percent, making them notoriously susceptible...

Threaded neodymium pot magnets combine a traditional threaded male or female attachment into the actual cup of a north or south facing pot magnet. Threaded pot magnets are ideal for holding signs, tools and fixtures as well as for other magnetic closure, clamping, fastening, machining and retrieval applications. Here is a list of the most common uses for these kinds of magnets: Holding Fixtures: The threaded component allows these magnets to be easily attached to fixtures, jigs, and machinery. They can be screwed or bolted into place, providing a secure and reliable hold. This makes them useful for holding workpieces,...

In the world of neodymium magnets, the air gap refers to the precise distance separating a rare earth magnet and its intended attachment surface. In most cases, this intended surface would be another magnet or ferromagnetic object, such as a steel disc.Air gaps are a big deal because they give you an effective way to manipulate, calibrate and control the strength or pull force of a magnet and magnetic attachment in your application. The way it works is relatively simple: if you want a magnet to perform with its maximum pull force, it has to be as close as possible...
