High Temperature Resistant Iron Ore Magnetic Separator

2019-12-13neodymium has a negative coefficient, meaning the coercivity along with the magnetic energy density bhmax decreases with temperatureeodymium-iron-boron magnets have high coercivity at room temperature but as the temperature rises above 100 c 212 f, the coercivity decreases drastically until the curie temperature around 320 c or.
