I've read this question. It's about how to obtain the maximum inductance from a transformer: How do I use a transformer as an inductor?
Now, I would like to use the primary coil only as an inductor to study some basics about inductors. I'm going to build simple LR, RLC filters and other circuits.
If I changed the frequency or the components of the circuit that contains the primary coil, will the secondary coil change the inductance of the primary coil?
I need the primary coil to have a fixed inductance and behave like a normal coil.
The secondary coil is open circuit and not loaded.
I imagine that I can remove the secondary coil out of the core. Will the inductance of the primary coil change? This question will help me understand mutual inductance better.
