Hengdian Dongyang City, Kim Dae magnetic factory ----- magnetic tips: 1 magnetic field: the creation of space for the magnetic poles of the magnetic field effect .2 magnetic field strength:. (H) energized coil to produce a magnetic field strong magnet the size of a local factory, .H field size per unit length of the coil turns is n is flowing through the solenoid current I (A) generated by the magnetic flux density = n * I3 B:. vacuum permeability μ is multiplied with the magnetic field strength B = μ * H4 flux ∮:. magnetic flux density .∮ certain area through which = B * S (S for the unit area) 5 maximum energy product BH (max):.. refers to the minimum volume of .6 to get the strongest magnetic field coercive Force H: refers to the state of powerful magnets are magnetized supply plant, by applying a reverse magnetic field strength is achieved if the magnetization reversal of the magnetization reversal is needed by moving the magnetic domain walls is performed hinder movement of the magnetic domain wall. The force is .7 coercivity remanence B:. from saturation magnetic body magnetic field (including from the back field) decreases monotonically along the saturation hysteresis loop to zero magnetic induction (flux density) 8 surface. Magnetic field: magnetic induction of the permanent magnet surface to a specified location .9 magnetic anisotropy: in different crystallographic directions powerful magnet factory Which affordable, easy magnetization direction and the presence of hard magnetization direction it consists entirely of material nature itself decision Hengdian Dongyang Kim Dae magnetic ----- how to define the performance of the magnet? Mainly has the following three performance parameters to determine the performance of the magnet: remanence Br: permanent magnet magnetized to technical saturation, and after removing the external magnetic field, 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 (magnetic poles of two spaces) established by the 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.
