Strong neodymium block magnets for motors

Sintered Neodymium Iron Boron (NdFeB), the most powerful Rare Earth magnet available today, possesses high energy ranging from 8MGOe to 52MGOe and wonderful coercive force. As the third generation of Rare Earth permanent magnet, NdFeB products are quite a bit less expensive and are mechanically stronger and less brittle than SmCo, also density of NdFeB products is about 13% smaller than SmCo products. Because NdFeB magnets are more prone to oxidation than any other magnet alloy, for most applications, coating or plating the magnets is recommended.

Strong Neodymium Block Magnets
Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family. Neodymium block magnets have the highest magnetic properties and are the most powerful commercially available magnets today. Because of their magnetic strength, neodymium block magnets are the preferred choice for many consumer, commercial and technical applications.
The NdFeB Neodymium block magnets could be NdFeB Neodymium rectangular magnet or NdFeB Neodymium square magnets

Handle with care!

Please use caution when handling magnetized neodymium magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.
