strong permanent ndfeb magnet for speaker

The character designation of sintered NdFeB magnets is composed of NDdFeB, the chemical symbols of neodymium, ferrum and boron,and two magnetic properties. The number in front of the solidus refers to the maximum magnetic energy product, symbol BH max and unit kj/m. The number after the solidus refers to one-tenth of magnetic polarization intensity coercivity, symbol Hcj and unit KA/m, rounded to the nearest integer.
