磁通密度表征磁场的一个物理量。又称磁感应强度。它是矢量,可由磁场中作用于电流元I┡dl┡上的力dF(即安培力)来定义。若以B代表磁通密度，则有dF＝Idl×B由公式可见，电流元所受之力垂直于Idl与B所在的平面，其方向按右手螺旋规则确定，即由Idl沿小于π的角度转至B时右手螺旋前进的方向。力的大小为ㄧIdlㄧㄧBㄧ·sin(B,Idl)。这样就可以由载流导线在磁场中受到的力确定磁场中的B。B在国际单位制中的单位为特 [斯拉]，在CGS制中为高[斯]。1特相当于104高斯。H.A.洛伦兹在1895年提出：以速度&υ运动的电荷q在磁场中受力与电流元的受力相仿，有F＝q&υ×B这个力称为洛伦兹力，理论上亦可作为B的定义公式。如果产生磁场的电流是已知的，则真空中各处的磁通密度可由毕奥－萨伐尔定律给出.式中l为电流I的路径，r0为自电流元指向观察点的单位矢量，r为二者之间的距离，μ0为真空磁导率。穿过一面S 的磁通为Φ式中α 是B与dS的夹角。在国际单位制中，磁通的单位为韦伯(Wb)。
