No, there is a geometric saturation. You can't use the better permeability in reality.
The optimum length to width relation is about 6 to 10 for ferrite rods. Here is a diagram: http://ehydra.dyndns.info/NG/time-nuts/Pettengill%20002.jpg This is one of the classics in my link list: http://www.bentongue.com/xtalset/29MxQFL/29MxQFL.html - Henry li...@lazygranch.com schrieb:
Wouldn't the difference be directly proportional to the relative permeability? If so, the difference would be more like 125, not 10, depending on core material.
