Greetings,(adsbygoogle = window.adsbygoogle || []).push({});

I have read the explanation on this forum here: https://www.physicsforums.com/showthread.php?t=441637 which discusses Faraday's Law of Induction, but I'm having a hard time understanding how to extrapolate that to my problem.

My goal:

Construct a circuit that measures ambient magnetic field strength, i.e., for finding wires, or determining if the ambient field strength is above a recommended (and likely arbitrary) background level of .5 Gauss.

I have a great deal of electronics experience, but, frankly, I'm terrible with math. Construction of the circuit is quite simple (I have a working spice model at any rate) but where Faraday's Law enters the picture is this:

-Assume the "probe" I've placed in this device is a 1mH inductor

-I'm expecting this probe to produce a voltage I can measure, likely in micro or millivolts

So, can anyone give me a working example that would help me understand this? For instance, if my 1mH inductor was placed into a field of .5G strength coming from a 60Hz power line, what voltage would be induced on the probe?

Thanks,

-John
