Hi :

I take a strip of copper, width w and thickness t, wind a spiral coil of N turns with an inner diameter d1 and an outer diameter d2 (no iron, just plastic spacers and air).

Does anyone know a method (numerical or closed-form) for determining the inductance ?

There are a few Java calculators for spiral coils online, but it's not clear if they refer to wire or strip in a spiral.

Thanks
Gary


As long as the thickness of the coil (the width of the strip) is less than the inner diameter of the coil, it doesn't make much difference if its wire or strip.
