Thank youu so much it's really good to understand! I have a question, if there is an AC source instead of a voltage source, how do I get a phi function? Should I get the voltage with v= Ldi/dt and apply Faraday's law?

Thank you for your question. I will assume that the question is how to calculate phi if we have current signal waveform. Answer: If we assume the magnetic circuit is linear magnetic circuit, the following relationship can be used: Bsi = L x i where Bsi = N x phi . Therefore, the magnetic field phi can be calculated as follows: phi = (L/N) x i ( Note: the magnetic field and the current are in phase if the current sinusoidal waveform) Hope this answer your question
