I am thinking about winding a coil or two and I have some toroid cores and was wondering if anyone can tell me what the effect of using a longer core vs a short core will have. Intuitively, I suspect that if one core is twice as long as another, it would have twice the inductance, number of turns and wire size being equal, but the wire length would nearly double. I couldn't find on Google, maybe I didn't know the right question.
