磁通量磁通量magneticflux表征磁场分布情况的物理量。通过磁场中某处的面元dS的磁通量dΦB定义为该处磁感应强度的大小B与dS在垂直于B方向的投影dScosθ的乘积，即dFB=BdScosq式中θ是面元的法线方向n与磁感应强度B的夹角。磁通量是标量，θ＜90°为正值，θ＞90°为负值。通过任意闭合曲面的磁通量ΦB等于通过构成它的那些面元的磁通量的代数和，即对于闭合曲面，通常取它的外法线矢量（指向外部空间）为正。磁场的高斯定理指出，通过任意闭合曲面的磁通量为零，即它表明磁场是无源的，不存在发出或会聚磁力线的源头或尾闾，亦即不存在孤立的磁单极。以上公式中的B既可以是电流产生的磁场，也可以是变化电场产生的磁场，或两者之和。磁通密度是通过垂直于磁场方向的单位面积的磁通量，它等于该处磁场磁感应强度的大小B。磁通密度精确地描述了磁力线的疏密。通量概念是描述矢量场性质的必要手段，通量密度则描述矢量场的强弱。磁通量和磁通密度，电通量和电通密度都是如此。在国际单位制（SI）中，磁通量的单位是韦伯（Wb）。
