(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using two solenoids on a ferromagnetic core, I made a primitive transformer and graphed this graph of voltage against frequency which is attached.

2. Relevant equations

[What I'm looking for.]

3. The attempt at a solution

What I am having trouble is, what equation describes the linear pattern in the earlier part of the curve? There's one on wikipedia, V=4.44f, but why doesn't this relate to V1/N1=V2/N2, eqn for transformer in an alternating current?

And I know that the voltage drops off because of hysteresis which is inversely proportional to voltage, and that the delaying effects of hysteresis become more and more significant to the shortening period as frequency increases. What function do I need to model this behaviour?

I would be really glad if anyone would help, because the lab's due Monday.
