The King of Magnets: Neodymium Magnet
Neodymium Iron Boron (NdFeB) magnets, commonly known as neodymium magnets, are the strongest type of permanent magnets available today. They are made from an alloy of neodymium, iron, and boron, forming a tetragonal crystalline structure.
First developed in the 1980s, these magnets have quickly gained widespread use due to their high magnetic strength, excellent performance-to-size ratio, and cost-effectiveness. NdFeB magnets are widely used in various industries, including electronics, automotive, renewable energy, medical devices, and more. For example, they are critical components in electric motors, wind turbines, hard drives, and speakers.
Despite their strength, neodymium magnets are relatively brittle and prone to corrosion. To enhance durability and longevity, they are typically coated with protective layers such as nickel, zinc, or epoxy resin.
Their exceptional properties make them an indispensable material in modern technology and innovation.
