一、明确“磁通量”这个概念的定义和意义定义:设在磁感应强度B的匀强磁场中,有一个面积为S且与磁场方向垂直的平面,磁感应强度B与面积S的乘积,叫做这个平面的磁通量,简称磁通。数学表达式为:准=BS,适用条件是B与S平面垂直;当B与S存在夹角θ时,准=BS·sinθ;在国际单位制中,磁通量的单位是韦伯,符号是Wb,1Wb=1T2·m2。意义:可以用磁感线的条数形象地加以说明,在同一磁场的
First, a clear “magnetic flux ” the definition of the concept and meaning of the definition: set in the magnetic flux density B uniform magnetic field, there is an area of S and perpendicular to the direction of the magnetic field plane, the magnetic induction of the product of the area B and the area called S This plane magnetic flux, referred to as flux. The mathematical expression is: quasi = BS, where B is perpendicular to the S plane; quasi = BS · sinθ when there is an included angle θ between B and S. In the International System of Units, the unit of magnetic flux is Weber, the symbol is Wb, 1Wb = 1T2 · m2. Significance: You can use the number of lines of magnetic induction to illustrate the image, in the same magnetic field
