磁通量

图2:曲面法矢量的矢量场。
图3:空间中的矢量场F ( r, t )以及曲面Σ。∂Σ为曲面Σ的边界,以速度v运动。考虑矢量场在曲线∂Σ上的积分。
Flujo magnético por una espira.

磁通量,符号为 \Phi_m,是通过某给定曲面的磁场(亦称为磁通量密度)的大小的度量。磁通量的国际单位制单位是韦伯。

给定曲面上的磁通量大小与通过曲面的磁场线的个数成正比。此处磁场线的个数是个“净”数量,即从一个方向上通过的个数减去另一个方向上通过的个数。当一个均匀磁场垂直通过一个平面,磁通量即是磁场与该平面面积的乘积。当均匀磁场\mathbf{B}以任意角度通过一个平面,磁通量即是磁场与该平面面积\mathbf{a}的点积。

其中,\theta是磁场\mathbf{B}和平面面积法矢量\mathbf{a}的夹角.

在一般情况下,磁通量是通过磁场在曲面面积上的积分定义的(见图1和图2)。

其中,\Phi_m \ 为磁通量,\mathbf{B}为磁感应强度,S为曲面,\cdot为点积,d\mathbf{S}为无穷小矢量(见曲面积分)。

Magnetic flux 磁通量

The magnetic flux through a surface—when the magnetic field is variable—relies on splitting the surface into small surface elements, over which the magnetic field can be considered to be locally constant. The total flux is then a formal summation of these surface elements (see surface integration).Each point on a surface is associated with a direction, called the surface normal; the magnetic flux through a point is then the component of the magnetic field along this direction.
Some examples of closed surfaces (left) and open surfaces (right). Left: Surface of a sphere, surface of a torus, surface of a cube. Right: Disk surface, square surface, surface of a hemisphere. (The surface is blue, the boundary is red.)
For an open surface Σ, the electromotive force along the surface boundary, ∂Σ, is a combination of the boundary's motion, with velocity v, through a magnetic field B (illustrated by the generic F field in the diagram) and the induced electric field caused by the changing magnetic field.

In physics, specifically electromagnetism, the magnetic flux (often denoted Φ or ΦB) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface. The SI unit of magnetic flux is the weber (Wb) (in derived units: volt-seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the magnetic flux.
