Yep, that's the setup I used for the Fasel vs Crybaby test back in 92 or 93.

I did. That was the substance of the original test I did. I still have the harmonic profile in my test data, so the test data already exists.  
 
 
 
I've actually done this experiment on a ferrite wound core, but I didn't have access to the proper lab equipment, so the results were equivocal. Sounded pretty good, though.  
 
 
 
The key to the harmonic generation will be the shape of the core material BH curve's knee. Both materials come in a variety of knee curves, so it'll probably depend on who made the inductor under test.
