Inductor

[Piyush Ramraika]

I want to make an inductor coil using coil but i am not getting the formula for the design and measuements. Can anyone help

What type of coil? wound on what? ferrite, iron, air

Sir a have 24SWG coil and i am going to use air core

What is "24SWG"?

What is "24SWG"?

Morning Mike,
Its Imperial, Standard Wire Gauge, an olde Brit standard.

Your even going older..

What inductance value are you looking for?
A single layer solenoid is easiest to calculate accurately, but if you need higher inductance values than what can be practically obtained from a single layer winding then there are some multi-layer formulae that are reasonably accurate. There is no single formula that is good for every geometric configuration.


BTW, according to this online calculator:
https://www.coilwindingmachines.eu/engineers_corner/awg_swg_converter.html
#24SWG = .559 mm which would be equivalent to #23.2 AWG

Here's a calculator: https://www.circuits.dk/calculator_multi_layer_aircore.htm

Here's a similar formula from a Tesla site: https://www.pupman.com/listarchives/1998/April/msg00062.html

Both appear to have empirical elements.
