Hey guys ! I was hoping for some help trying to pin down some datasheet with any Inductance equations for the a lamination I purchased. I got it from a pretty shady shop with no data on manufacturer , composition or even part number. I have determined the dimensions do line up with the EI-114 type.
It seems to be some form of silicon steel to the eye , although Si% is hard to determine. I would assume somewhere around 4% as that is the most common for purchasable domestic transformers in our country. They have a thickness of ~0.5mm (calculations show somewhere around 0.496mm).
Ultimately what I'm looking for is an equation that will show what N primary turns is needed to get some L Inductance value in the core. For example, from Robert G. Wolpert's book he found a catalog for his lamination with the equation L = .9283 * 10^-8 * K * U ; where K is the stacking factor and U is permeability of core material.
Thank you for the help !

The most relyable source is to just measure it. From the resulting values you can calculate to the range you need.
