I thought of another important thing. The induced current in the second conductor would in turn induce a current in the first conductor. So there would be a mutual inductance effect that makes this problem much more complicated than I was making it out to be.

Thank you for the detailed response. You communicated more eloquently what I was trying to say. So the induced current does in fact lag the driving current by 90 degrees, which is evident if you compare FIG1 to FIG4 like you said. In the time domain, this translates to currents that flow...

I never said that was Lenz's Law. You need to read more carefully. I agree that the currents will be 90 degrees out of phase, but that does not equate to "perfectly opposite currents". Opposing currents would be 180 degrees out phase. Equal magnitudes, opposite signs. I just thought of a...

I have a question regarding Lenz's Law. In many of the passages that I read about Lenz's Law, I see this: "If the magnetic field of current i1 induces another current, i2, the direction of i2 is opposite that of i1." I don't think this is always true, though. For example, let's assume we have...

Hi everyone! This is my first post here, and I will start with a question: I used the wattmeter-voltmeter-ammeter method to measure both the original power factor of a compressor motor and its power factor after installing PFC caps. The values, respectively, were 0.78 and 0.91. I am 100%...
