摘要: 提出用磁通元電場(chǎng)疊加法求解渦旋電場(chǎng),利用該方法推導(dǎo)出了空間旋轉(zhuǎn)平面區(qū)域產(chǎn)生的渦旋電場(chǎng)的時(shí)域表達(dá)式,驗(yàn)證了磁通元電場(chǎng)疊加法求解渦旋電場(chǎng)的正確性。

Abstract: The electric field summation method of magnetic flux element is proposed to calculate eddy electric field. Based on this method, the time domain formula of eddy electric field generated by plane area rotating in constant magnetic is derived. It also indicates that calculation of eddy electric field using electric field summation method of magnetic flux element is correct. -
