The Romer-Lewin ring with inductors (part 3 correction)

- This should have been part of the fourth video, where I show the agreement of theory and practice, but apparently my PC cannot produce videos bigger than a certain amount of MB, or seconds, or whatever.
I need to split each video in many small chunks, and I will eventually give up making videos, but for the time being, here are the voltmeters showing the correct voltages (one of which needs to be adjusted due to the bandwidth limit of the slow voltmeter).
in the previous Part 3 REBOOT video, the UT139C showed a voltage of 50.5 mVrms across the bigger inductor. This is not the correct value that can be reproduced multiple times in the experiment. When corrected by the multiplicative factor 2.02, it will result in 103 mVrms , which happens to be the full EMF.
I am not sure how I got that spurious measurement but here is the two voltmeters showing the correct values:
UT61E: 84 mV (no need for correction)
UT139C: 40.6 mV (once corrected it becomes 82.1mV mV)
All values are rms.
