在电磁感应现象中产生感应电动势的那部分导体或者回路相当于电源,所以电磁感应问题往往与电路问题联系在一起。解决与电路相联系的电磁感应问题的基本方法是:(1)确定感应电流的方向;(2)画出等效电路;(3)运用全电路的欧姆定律、串并联电路的性质、法拉第电磁感应定律等公式联立求解。而正确地作
The part of the conductor or circuit that generates the induced electromotive force in the electromagnetic induction phenomenon is equivalent to the power source, so electromagnetic induction problems are often associated with circuit problems. The basic methods to solve the electromagnetic induction problem associated with the circuit are: (1) determine the direction of the induced current; (2) draw the equivalent circuit; (3) use the full-circuit Ohm’s law, the nature of the series-parallel circuit, Faraday’s electricity The law of magnetic induction and other equations are solved simultaneously. Correctly
