补充资料：磁感应强度
| 磁感应强度 magnetic induction 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。 点电荷q以速度v在磁场中运动时受到力f 的作用。在磁场给定的条件下，f的大小与电荷运动的方向有关 。当v 沿某个特殊方向或与之反向时，受力为零；当v与此 特殊方向垂直时受力最大，为fm。fm与｜q｜及v成正比，比值  与运动电荷无关，反映磁场本身的性质，定义为磁感应强度的大小，即 。B的方向定义为：由正电荷所受最大力fm的方向转向电荷运动方向 v 时 ，右手螺旋前进的方向 。定义了B之后，运动电荷在磁场 B 中所受的力可表为 f ＝ qv×B，此即洛伦兹力公式。除利用洛伦兹力定义B外，也可以根据电流元Idl在磁场中所受安培力df＝Idl×B来定义B，或根据磁矩m在磁场中所受力矩M＝m×B来定义B，三种定义，方法雷同，完全等价。 在国际单位制（SI）中，磁感应强度的单位是特斯拉，简称特（T）。在高斯单位制中，磁感应强度的单位是高斯(Gs )，1T＝104Gs。由于历史的原因，与电场强度E对应的描述磁场的基本物理量被称为磁感应强度B，而另一辅助量却被称为磁场强度H，名实不符，容易混淆。通常所谓磁场，均指的是B。 |
