The boundary value problem on the magnetic vector potential a is derived by introducing the magnetic vector potential a and using maxwell ' s equations 通過引入矢量磁位a并利用麥克斯韋方程組推出了以矢量磁位a為求解對象的邊值問題。
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帶有限長磁芯的放置式通電圓柱線圈的阻抗解析表達(dá)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 隨著磁芯高度和半徑的增大,線圈阻抗增量增大,當(dāng)磁芯高度超過某一值時,線圈阻抗趨于穩(wěn)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,應(yīng)用疊加原理,并對圓環(huán)線圈進(jìn)行積分,求得各場區(qū)通電圓柱線圈的矢量磁位表達(dá)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.
