Re: [EVGRAY] Florist wire and BiTT core

Body

Hi Kone, guys
If you are going to make a core this way, it is important to make sure the
outer loop is about twice the thickness of the inner drive loop.
This is to make it easier for the back EMF flux to go around the outside
loop rather than re entering the drive loop..... affecting the input
impedance on load.

The setup works best when the permeability of the centre drive loop
magnetic core circuit is high in comparison to outer loop.
So permeability of the outside magnetic loop circuit  (where the load coils
are mounted) ..nice low permeability needed here.
Also thickest cross section area and shortest magnetic path length from one
load coil to the other load coil ..if possible.

The one in the photo posted doesn't seem to have sufficiently thick outer
loop.
