It is pointed out that the self-induction coefficient is relative to the current frequency in the actual conductor circuit, even if there is not any magnetic medium.
指出在无磁介质存在的条件下，实际导体回路的自感系数也与电流频率有关。
The current peak phenomenon is usually shown in the electrifying self-induction experiment, but in the present documents, this phenomenon has not been perfectly explained.
通电自感演示实验中存在电流尖锋现象，但始终没有完善的理论解释。
The current intensity of variations will produce self-induction when a closed coil moves in magnetic field. Must be attended to the contribution of the current by self-induction to total current.
闭合线圈在磁场中运动，线圈中的电流变化将产生自感，自感电流对总感应电流的贡献是不容忽视的。
