I'm curious about making humbuckers out of differing coils. Mismatched sizes, or different wire gauges, a larger "center" diameter to the coil, combinations there of, what have you.
Just playing around, really.
So I'm curious what I need to take into consideration to keep the two coils humbucking. There's a thread a ways back, where Joe Gwinn talks about what sort of difference we hear as humbucking enough, and a bit of math concerning the differences in hum voltages that will make a 20dB change in hum volume.
Ignoring for a moment how the music signal is going to be picked up; what calculates how much hum a coil will pick up? I assume it may be fairly complex math; but I'm interested in learning what I can. Seems like some of the radio antenna design books my father has might point me in the right direction, but it's aimed at a different concept a bit.
Is it total area of the surface of the wire? Number of turns, or something else? I understand it may be more involved than someone wants to explain in a forum post, but if someone wants to point me in the right direction so I know where to go with my research, or at least give me a tip as to the factors involved, that'd be awesome.
Thanks!
