NEODYMIUM-IRON-BAR MAGNETS (NeFeB)
NdFeB magnets are the magnets which are manufactured to the present with the highest energy and permanent induction after the SmCo alloys. The most important disadvantages of NdFeB magnets are the low temperature of Curie and being expensive.
It is used in space crafts where volume and weight are crucial, such as Samariums; in drive motors which are needed in aircrafts and robotics; in iron ore enrichment seperators; in making pots and in making magnetic bars.
CHARACTERISTICS OF SINTERED NdFeB MAGNET
1 T(Tesla) = 10 kGs (KiloGauss) = 104G(Gauss)=, 1 kOe =103 Oe = 79.6 kA/m, 1 MGOe = 7.96 kJ/m³
