Summary

Description
English: Drawing of Michael Faraday's 1831 experiment showing electromagnetic induction between coils of wire, using 19th century apparatus, from an 1892 textbook on electricity. On the right is a liquid battery that provides a current that flows through the small coil of wire (A) creating a magnetic field. When the small coil is stationary, no current is induced. However, when the small coil is moved in or out of the large coil (B), the change in magnetic flux induces a current in the large coil. This is detected by the deflection of the needle in the galvanometer instrument (G) on the left.
中文：插图取自一本1892年的电学教科书，描绘了1831年迈克尔·法拉第展示线圈之间如何产生电磁感应的实验。实验装置为19世纪的器材，右侧的液体电池为小线圈（A）提供电流，从而产生磁场。小线圈静止时不会产生电流；但当小线圈移入或移出大线圈（B）时，磁通量的变化会引发感应电流产生。电流的产生是通过左侧检流计（G）中指针的偏转检测的。
