Calculate current through tank circuit on induction heater
.
Did a lot of twisting and used a common mode choke. I was able to get the measured voltage down from 3.4v to 0.5v. This gives a current...

I thought this is what you meant. Why the single turn from the lead on the left? Why not have both test leads meet midway in the section...
