对感生电场计算方法的探讨

对于感生电场的计算问题,在大学电磁学教材中一般都是利用反证法证明螺线管管内外的E感线都是与螺线管轴线相垂直的同心圆.笔者在此利用解析法和类比法两种方法来证明螺线管管内外的E感线都是与螺线管轴线相垂直的同心圆,并在此基础上计算了E感的大小,以供教学参考.

Discussion on Calculation Method of Induced Electric Field

For the calculation of induced electric field,in the university electromagnetics teaching materials,the counter-evidence method is generally used to prove that the inner and outer lines of the solenoid tube are concentric gardens perpendicular to the axis of the solenoid.Here,the author uses the analytical method and the analogy method to prove that the inner and outer lines of the solenoid tube are concentric gardens perpendicular to the axis of the solenoid,and the size calculated on this basis is used for teaching reference.
