"The density of the lines indicates the magnitude of the field, the lines Being crowded together where the magnetic field is strong. The SI unit for magnetic flux is the weber." 线的密度表示磁场的强度,磁场强的地方磁力线就密集。磁通量的国际单位是韦伯。电通(量)密度,电移位密度
A cgs unit of magnetic flux equal to the flux perpendicular to an area of 1 square centimeter in a magnetic field of 1 gauss. 厘米克秒制磁通量单位等于在一高斯的磁场中垂直通过面积为一平方厘米的磁通量。
A unit of magnetic flux density equal to one weber per square meter. 磁通量密度单位等于每平方米韦伯。
