一、W=((△Φ)~2)/(R·△t)是电磁感应现象中的普适公式吗?贵刊2008年第4期中“浅谈安培力做功的一般量度式((△Φ)~2)/(R·△t)”一文认为,在电磁感应现象中,((△Φ)~2)/(R·△t)是安培力做功、电路中产生的电能的一般量度式,且“不依赖于磁场是否匀强;不依赖于相对切割速度是否匀速;不依赖于磁场的变化是否均匀.可见,它具有普适性,适用于多种情况,它是电磁感应现象
A, W = ((△ Φ) ~ 2) / (R · △ t) is a universal formula in the phenomenon of electromagnetic induction? No.4, 2008, In the electromagnetic induction phenomenon, ((ΔΦ) ~ 2) / (R · Δt) is the work done by the amperage, and the electric energy generated in the circuit The general measure, and ”does not depend on the magnetic field is uniform; independent of the relative cutting speed is not constant; independent of changes in the magnetic field is uniform.It can be seen, it is universal, suitable for many situations, it is electricity Magnetic induction phenomenon
