NdFeB magnets are judged by several key magnetic properties: remanence (Br), intrinsic coercivity (Hci), and maximum energy product (BHmax). Remanence (Br) tells you the magnet’s field strength after magnetization.
What are the magnetic performance parameters of NdFeB magnets?
NdFeB magnets are judged by several key magnetic properties: remanence (Br), intrinsic coercivity (Hci), and maximum energy product (BHmax). Remanence (Br) tells you the magnet’s field strength after magnetization. Intrinsic coercivity (Hci) shows how well the magnet resists demagnetization, which is important for use in high temperatures or strong external fields. The maximum energy product (BHmax) is a measurement of the magnet’s overall power and efficiency. Sometimes, customers also look at temperature coefficients to understand how stable the magnet is at different temperatures. These values are standard on data sheets and help users choose the right magnet for their needs.
