About Hiest
The performance parameters of sintered NdFeB magnets mainly have three key magnetic properties including remanence, coercivity and max. energy product.
Remanence (B) - Measures the strength of the magnetic field. Neodymium magnets are highly remanent, which means their magnetic field has a very high strength.
Coercivity (Hci) - This is the resistance to demagnetization of the material. Neodymium magnets have high coercivity, which means they are very resistant to demagnetization.
Maximum energy product (BHmax) - This is the density of the magnetic energy of a permanent magnet, characterized by the maximum value of the magnetic flux density (B) times the magnetic field strength (H). Neodymium magnets have a very high energy product.
NdFeB (also known as neodymium magnet or Neo magnet) is the most widely used type of rare-earth magnet. It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd₂Fe₁₄B tetragonal crystalline structure. Neodymium magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, switches and loudspeakers.
