Reply #2760. A short snippet from this reply, "B is proportional to the integral of voltage across an unloaded inductance model on the nonlinear portions and B is proportional to the voltage related by a constant on the linear portions, while H is proportional to the current through the device. e = n * (dphi/dt)
B = (µ0 * µr) * H, and H is proportional to current, so why is not B proportional to current? Well, it is a function of current, so in a linear core or in that region where the core is linear, then it is related by a constant (As you can see, the voltage and the current are both related by a constant or by a "specific number" on the linear portions). In the region where the core material is nonlinear, then the core effective permeability is a function of current but not a linear one".
Reply #2773. A short snippet from this reply, "The 4th and 5th paragraphs below the second image of the page, Magnetics - Core/transformer conversation , you will find how "B" is related to the voltage by a constant and "H" is proportional to the current when you're on the linear portions of the curve".
In the end, the trolls and disinfo agents won, as always. I'm not saying everything I post is correct, but I don't intentionally post information in which I know is incorrect. Ash, thanks for confirming my guess was right or atleast maybe in the general ballpark.
[Edit:] The author in the "Magnetics-Core/transformer conversation" link above, also wrote the B2 Spice v.5 Electronic Circuit Simulation Software that is well known and used, so this guy knows what he's talking about. The trolls said I was wrong, but what I posted was nearly word for word coming from this expert on cores and transformers. The red text above does not appear in the original post, but was added to help clarify how both the voltage and current are related by a constant in order to find the resonance of the system.
