Neodymium Magnets are considered the strongest and smallest magnets. They were invented in 1982 by the cooperation between three big companies and research facilities in China and USA. The secret component that gives their capabilities is the Neodymium. It is one of the rare earth elements. When it is mixed with Iron and Boron, then magnetized, it gives as the neodymium magnets which are also known as NIB magnets and also “NeFeB” magnets.
Being strong and small in size made them a new revolution for all technological devices. Last year, around 550 tons of neodymium magnets were manufactured. They have several uses ranging from earphones for MP3 players to big machines and motors. In earphones, it was hard to accomplish high sound enough for users and small pieces to be fitted inside the external ear, with the help of neodymium magnets, those devices have been made possible. These magnets also helped in improving sound quality for desktops and speakers too. In addition neodymium magnets are heavily used in electrical motors -cars, scooters and bicycles.
What makes these magnets so strong?
By mixing neodymium, iron and boron, we get special metal slug, which then needs to be magnetized by very strong electromagnetic field. The result of this process is creating the strongest and most permanent magnets currently available. The neodymium element is key for these magnets as they have very strong magnetic fields which range in power from N24, the lowest, to N55 which is the strongest. The biggest drawback of these magnets is that they start to loss their power at temperatures of 80 degrees Celsius, which is considered low in comparison with other types of magnets.
About Stanford Magnets.
Based in California, Stanford Magnets has been involved in the R&D and sales of licensed Rare-earth permanent magnets, Neodymium magnets and SmCo magnets, ceramic magnets, flexible magnets and magnetic assemblies since the mid of 1980s. We supply all these types of magnets in a wide range of shapes, sizes and grades.
