大家都知道,力学中力 F 做功的一般量度式为 W=F·scos θ;静电场中,静电力做功的一般量度式为 W=q·U;在直流电路中,电源做功的一般量度式为 W=q·E.但在电磁感应现象中,通常是用机械能的减少量等于转化而来的电能列出守恒方程来表征安培力做功的多少,而没有电磁感应现象中安培力做功的一般量度式.对电磁感应现象而言,由功能的转化方向及守恒可
As we all know, the general measure of force F in mechanics is W=F·scos θ; in electrostatic fields, the general measure of electrostatic force work is W=q·U; in a DC circuit, the general measure of power work is For W=q·E. But in the electromagnetic induction phenomenon, usually the reduction of mechanical energy is equivalent to the converted energy. Energy conservation equations are listed to characterize the work done by Ampere force, but there is no general work of Ampere force in electromagnetic induction phenomenon. Measurement type. For the electromagnetic induction phenomenon, the conversion direction and conservation of the function can be
