Sintered NdFeB magnets have the highest strength but are limited to relatively simple geometries and can be brittle. They are made by pressure forming the raw materials into blocks, which then go through a complex heating process. The block is then cut to shape and coated to prevent corrosion. Sintered magnets are typically anisotropic, which means they have a preference for the direction of their magnetic field. Magnetizing a magnet against the “grain” will reduce the strength of the magnet by up to 50%. Commercially available magnets are always magnetized in the preferred direction of magnetization. Radial Oriented NdFeB Ring Magnet.
Multi Poles Diametrically NdFeB Ring
Features: Super strong rare earth neodymium magnets – they are hard to separate once they get attracted to each other.

Neodymium(NdFeB) Magnet are widely used in many fields, such as motors, sensors, microphones, wind turbines, wind generators,
Neodymium magnets are very strong. Handling them with care is necessary to prevent personal injuries, property damages, and magnet damages. It’s not a TOY! Make sure to keep the magnets are out of reach children and pets, as small magnets will pose a choking hazard.
Neodymium magnets are brittle; they can be broken or can splinter in a collision. One should wear gloves and protective glasses when handling these magnets because splinters could disengage and fly from the magnets.
Normal Neodymium magnets will lose their magnetic properties if heated above 175°F (80° C).
