Faraday's law of induction clarifications - Area change over time
What confuses me is that the flux derivative is inside the surface
integral.
The partial derivative inside the integral comes from Leibniz Integral Rule (detailed below).
Consider generalized …

How to measure flux in transformer in LTspice?
None of them is correct.
flux1 looks more reasonable because flux2 uses unswitched windings as well.
Remember the transformer model:
simulate this circuit – Schematic created using CircuitLab
The c …

Why we use constant value of magnetic flux in transformers
Think of the transformer theoretical model (without parasitic elements):
simulate this circuit – Schematic created using CircuitLab
The ideal transformer (IDEAL TX above) has infinite magnetising i …

Magnetising Inductance / Primary Inductance
if the magnetising inductance (which the primary inductance) is defined as 100uH then why it is seperated as 100uH and 10mH on the primary ? This is my question.
Without the parasitics, a real-world …

Transformer modelling / coupled inductors
In the beginnig of V2 equation in the picture where does the n.Lm come from ?
The inductor's voltage-current relationship is:-
$$
v_L = L \ \frac{di_L}{dt}
$$
The voltage across the primary magnetis …
