What is a block neodymium magnet?
A square neodymium magnet is a strong magnet made of neodymium iron boron (Nd2Fe14B), with a rectangular or square shape. Neodymium magnets are currently one of the strongest known permanent magnet materials, widely used in various industrial and commercial fields, such as motors, speakers, hard disk drives, maglev trains, and various magnetic tools and equipment. Due to its strong magnetism and relatively small volume, square neodymium magnets are very popular in applications that require high magnetic field strength.
⚙
