Thanks Bill,
That makes sense, though to me it's much simpler (and no less accurate) to think of it as a single coil twisted 180 degrees in the middle than as thousands of single turn coils in series. As you said, the electrons don't care. In terms of inductance, yes, that's how I expect (and...
I've been looking up various definitions of "coil" in every dictionary I can find, and not one of them fits when applied to one lobe of the twisted coil. The only one that sort of fits, but only if you interpret it disingenuously, is "a series of loops". I think what is meant here is "a...
What is your definition of a coil? I'm not arguing that a single piece of wire equals a coil... if you wind one coil and then wind another continuously with one wire, that's two coils. That's not what I'm describing. If you take an oval coil and twist it into a figure 8 shape, it does not...
Thanks for your response. Each loop of the 8 is in proximity to a magnet; these magnets are arranged in opposite polarity to each other. There are other (proprietary) adjustments to account for the "dead spot" between the two magnetic fields. The arrangement is to cancel hum, the same way that...
Thanks... but in this case there is only one coil, so mutual inductance is undefined (in other words, it makes no sense). Twisting one coil into a fig 8 shape gives it some properties of two coils in series (e.g. hum cancellation) but that doesn't make it two coils. What I'm looking for is a...
Hi, I make guitar pickups. I'm not an EE. I've applied for a patent, and the patent examiner is having a hard time distinguishing the difference between a single coil twisted into a figure 8 shape and a pair of coils connected in series. I need some help making the case that these are...
