I am trying to design a Helmholtz coil, that will have an impedance of about 2 ohms (the reason for this being that I am going to hook it up to a audio power amplifier, so to get the same wattage delivered I'm modeling it like a speaker that is 2 ohms)
If it helps thinking of using this amplifier.
First let me detail my set up:
Function Generator -> Power Amplifier -> Helmholtz Coil
I'm trying to generalize this as much as possible, so going to try and talk about it conceptually, is the best way to control the impedance in the coil is to set up an RL circuit, where I have a variable resistor so I can adjust it in turn with the impedance? And should I do the RL circuit in parallel or series?
