I have this electromagnet with an iron core completely embedded in resin that I'm trying to reverse engineer. I had it tested for inductance with a specialized company that owes me a few favors, and they told me that when its coil is exited with a 1Khz@1V sinusoidal signal, their instruments would read a value of 1.0964 mH . And that when they measured its internal resistance, they'd read a value of about 0.60Ω ... I'm saying about this value, because it actually oscillated between 0.65Ω and 0.55Ω when measured with a high-accuracy multimeter... I'm thinking that the fluctuations have something to do with the reactance in the coil due to the small voltage/current that the multimeter needs to apply when making a measurement.
Is there a way to calculate the wire gauge and/or number of turns with this information? Or will I need to take it appart and find out?
