Rotating Magnetic Field's and Inductors.

Here is my new test device which uses the coils flyback to do work.

Same observation, it's more efficient with the coil and magnet rotor.

What do you mean by "efficiency?"   I asked you the last time you posted something and you did not answer so I am asking you again for this new posting.

What I am seeing in your scope captures is that without a rotor in place the current draw of the coil increases so your math trace shows increased power consumption of the coil.  That's pretty much expected.  I don't think I see any measurements for the back spike power.  So what information are we supposed to be getting from your scope captures?

I think you have my DUT mixed up with Luc's, as I have never had a recovery cap with a 1K ohm resistor--I have always had the second battery recieving the recovered energy.

I don't think so.
You posted this schematic here.

Aslo, I was writing about a 100Ω resistor, not 1K, because I heard/saw one in your video.

Your in the wrong thread. This thread i have always used the SSG circuit with second battery,not the schematic you posted. Read the very first post of this thread,and watch the very first video. The schematic you posted is from Luc's thread-not this one.

To go mixing up different schematics from different threads will only add confusion.

Hey Luc
The video is set to private--cant view it.

Yes, sorry about that. I forgot to make it public after I edited the two parts together.
Should be good to go now.

The circuit used is as below.
I inverted Ch2 to keep the scope shots looking like the previous or else the voltage would be inverted to the current?
