magnet filter

Mainly has the following three performance parameters to determine the performance of the magnet: remanence Br: permanent magnet technology magnetized to saturation, and after removing the magnet filter, called the retained residual magnetic flux density Br. Coercive force Hc: to technical saturation magnetization of the permanent magnet B is reduced to zero, the need to add a reverse magnetic field strength is called magnetic induction coercive force, referred to as coercivity magnetic energy product BH: represents the magnet gap space magnetic energy established by density, i.e., the static magnetic energy per unit volume of the air gap. As this energy is equal to the product of the magnet Bm and Hm, so called energy product. grid magnet: magnetic effect on the magnetic poles of the magnetic field space. Surface magnetic field: the magnetic induction of the permanent magnet surface to a specified location.
