I was just wondering where I could find some information about the characteristics of different types of coils e.g. winding methods and core materials.
I was looking at some audio links, and it is preferred to use air core coils for lower distortion in speaker crossovers. I don't know why there would be less distortion with an air core coil. With a core of greater magnetic permeability there would be a lower resistance which is also a plus for a speaker crossover (hence, that is why they prefer a large wire gauge) and a smaller coil size.
This got me thinking, what are the characteristics of other coil forms; toroid, bead, rod, etc. and different winding configurations, and why.
I'm not just wondering about coils in use for speaker crossovers, but in general. coils seem to be an important (and often critical) consideration under any application.
Anyone have some links or info for me?
