Neodymium Button Magnet
High quality Strong and Powerful Button Magnet for long lasting use. Neodymium magnet, also known as NdFeB or Neo magnet, is the strongest known type of permanent magnet, high power magnet. Because of their lightweight, strength and the consistency of their magnetization, Neodymium Magnets have become a popular choice for a wide variety of applications, from loudspeakers to magnetic therapy jewelry.
A rare earth magnet is made from an alloy of neodymium, iron, and boron.Unlike other types of magnets, Neodymium powerful magnet have a high resistance to demagnetization. They cannot be formed with conventional drilling, turning or milling processes, and must be ground before they are magnetized. Additionally, large or complex assemblies are usually magnetized prior to assembly. Standard tolerances for Neo magnetsare +/-.005 for ground dimensions. They require extremely high magnetizing fields and particular consideration must be given to this when designing complex assemblies.
Neodymium magnet can be magnetized in any direction as long as it is aligned properly. In some instances multiple pole magnetization is not possible; when it is possible, special fixtures are required.
Neodymium magnets have replaced Alnico and ferrite magnets in many applications where strong permanent magnets , super magnet are required, because their greater strength allows the use of smaller, lighter magnets.
