The raw material Ndfeb magnet main raw materials are: rare earth metals, rare earth metal praseodymium neodymium, pure iron, aluminum, boron and iron, and other rare earth materials Ndfeb magnet machining tools A slicing machine, cutting machine, flat grinding machine, double-sided machine, punching machine, chamfering machine, electroplating equipment. The process flow Ndfeb magnets, samarium cobalt magnet, alnico magnets, ferrite magnet production process is also different.Tell from technology, sintered ndfeb magnets and adhesive ndfeb magnets, we mainly speak of sintered ndfeb magnet. The permeance coefficient is mathematically equal to Bd/Hd. Calculation of the permeance coefficient allows the magnetics design engineer to determine the operating point of a magnet by construction of a load line from the origin of the BH curve at a gradient equal to the permeance coefficient. The intersection of this load line and the demagnetization curve (at the point (Hd, Bd)), is the operating point of the magnet.
