The Ultimate Guide to Using Neodymium Magnets: Tips, Tricks, and Applications
What are Neodymium Magnets?
Neodymium (NdFeB) magnets are a type of strong, rare-earth magnet made from a combination of neodymium, iron, and boron. They are known for their exceptional magnetic strength, corrosion resistance, and ability to produce a strong magnetic field. Due to these characteristics, neodymium magnets are used in a wide range of applications, from household items to industrial processes.
History of Neodymium Magnets
The development of neodymium magnets dates back to the 1980s when a team of scientists at General Motors’ Delco Division discovered the unique properties of neodymium-iron-boron alloys. Since then, the production of neodymium magnets has become a standard process, with numerous manufacturers around the world producing these powerful magnets.
