Strongest Magnetic Material Neodymium Magnet Block With Holes
Neodymium magnets, also known as Neo or NdFeB magnets, are a type of rare earth permanent magnets which made from Neodymium, Iron, Boron, and other minor elements. Neodymium block magnet is available in a wide range of dimension, grade, and coatings. It is generally specified according to the Length (L) x Width (W) x T (Thickness). The first two dimensions specify the pole face's size of each magnet, then the last dimension detail the distance between the N pole and S pole, or magnetization direction. Block magnet can be further classified to rectangular magnet, slab magnet, cube magnet, and square magnet in accordance with above three dimensions. Operating temperatures of Neodymium block magnet vary among material's grades and can be used for a huge variety of applications.
