Howdy. Does anyone have any info on how to calculate inductance and such for a spiral coil. (When I say spiral coil I mean a coil that is wound like a record; wound in 2 dimensions.) Or how about going the other way? I'm planning on making such a coil, and I know what the inductance should be, but I need to know how big to make it. Things that I know : - Inductance - Inside diameter. The coil will not start in the middle, so it will end up looking more like a flat doughnut. - Diameter of wire. Things I need to calculate : - Length of wire. - Number of turns (which is easily derived from length of wire). Is there anything I'm missing? If possible, please e-mail replies; I don't get a chance to read this news group very often. Thanks.
