The boundary value problem on the magnetic vector potential a is derived by introducing the magnetic vector potential a and using maxwell ' s equations 通过引入矢量磁位a并利用麦克斯韦方程组推出了以矢量磁位a为求解对象的边值问题。
Finally , the impedance analytical expression for the solenoid coil with a finite - length ferrite core carrying time - harmonic current is obtained through the magnetic vector potential 最后由矢量磁位得到带有限长磁芯的放置式通电圆柱线圈的阻抗解析表达式。
The main work is as follows : for the magnetic vector potential , the principle of calculus of variations is applied to convert the elliptical boundary value problem into 随着磁芯高度和半径的增大,线圈阻抗增量增大,当磁芯高度超过某一值时,线圈阻抗趋于稳定。
Then , using the principle of superposition and integrating the delta - coils , we can obtain the expressions for the magnetic vector potential caused by the cylindrical coils carrying current 然后,应用叠加原理,并对圆环线圈进行积分,求得各场区通电圆柱线圈的矢量磁位表达式。
In vector calculus, a vector potential is a vector field whose curl is a given vector field. This is analogous to a scalar potential, which is a scalar field whose gradient is a given vector field.
