磁感应感度，用B表示，又称为磁通密度，用来描述空间中的磁场的物理量。其定义公式为（百度百科）磁感应强度（magnetic flux density），描述 磁场 强弱和方向的基本物理量。是矢量，常用符号B表示。磁感应强度也被称为磁通量 密度或磁通密度。在物理学中磁场的强弱使用磁感强度（也叫磁感应强度）来表示，磁感强度大表示磁感强；磁感强度小，表示磁感弱。5、磁化曲线磁化曲线是表示物质中的磁场强度 H与所感应的 磁感应强度B或磁化强度 M之间的关系6、磁滞回线（）（6 磁滞回线 (hysteresis loop)：在磁场中，铁磁体的磁感应强度与磁场强度的关系可用曲线来表示，当磁化磁场作周期性变化时，铁磁体中的磁感应强度与磁场强度的关系是一条闭合线，这条闭合线叫做磁滞回线。）7、磁化率文档编码:CM2Q3O3Q2A3 HV10M8H9Y8X4

是标量；对于各向异性磁介质，磁化率是一个二阶张量。8、磁导率磁导率（permeability）：又称导磁系数，是衡量物质的导磁性能的一个物理量，可通过测取同一点的B、H值确定。二矫顽力-内禀矫顽力和磁感矫顽力的区别与联系矫顽力分为磁感矫顽力（Hcb）和内禀矫顽力（Hcj）。磁体在反向充磁时，使磁感应强度 B 降为零所需反向磁场强度的值称之为磁感矫顽力。但此时磁体的磁化强度并不为零，只是所加的反向磁场与磁体的磁化强度作用相互抵消。（对外磁感应强度表现为零）此时若撤消外磁场，磁体仍具有一定的磁性能。使磁体的磁化强度 M 降为零所需施加的反向磁场强度，我们称之为内禀矫顽力。内禀矫顽力是衡量磁体抗退磁能力的一个物理量，是表示材料中的磁化强度M 退到零的矫顽力。在磁体使用中，磁体矫顽力越高，温度稳定性越好。(2)退磁场是怎样产生的？能克服吗？对于实测的材料磁化特性曲线如何进行退磁校正？产生：能否克服：因为退磁场只与材料的尺寸有关，短而粗的样品，退磁场就很大，因此可以将样品做成长而细的形状，退磁场就将会减小。文档编码:CM2Q3O3Q2A3 HV10M8H9Y8X4 ZT6T7D9B7G2文档编码:CM2Q3O3Q2A3

在中部，则为载流螺线管模型，有H=n*I,由 n=200/0.2，I=0.5A,所以有H=500A/m。14某一铁的旋转椭球长轴为1毫米，短轴直径为 0.1 毫米，饱和磁环强度为u0Ms=2.1T,求长轴和短轴方向的退磁场。解:长轴/短轴=1/0.1=10 查表可知，当椭球的的纵横比为10 时，沿长轴的退磁因子Nz=0.0203，又 Nx+Ny+Nz=1，所以 Nx=Ny=0.48985.由退磁场公式：长轴退磁场Hd1=NMs=0.0203*2.1=0.04263Am 同理短轴退磁场Hd2=10.286859Am 文档编码:CM2Q3O3Q2A3 HV10M8H9Y8X4 ZT6T7D9B7G2文档编码:CM2Q3O3Q2A3 HV10M8H9Y8X4 ZT6T7D9B7G2文档编码:CM2Q3O3Q2A3 HV10M8H9Y8X4
