So I need reference inductances (to be tried on different circuits). So I decided I'd make a multi-tap inductor. Now, it's gonna have different layers of winding... But, I'm not sure how to pick the proper cross area thickness of the magnetic core. I need to make sure it creates a large enough magnetic field to reach all layers of winding.
These are the rough parameters for the multi-tap inductor:
Magnetic core:
Material: Electrical steel, so μ = 0.005 (But can be swapped with anything else. For now it's for storing magnetic flux from a pulsed DC)
Core dimensions (for now): 40mm L; 5mm D
Winding:
12 layers of winding, the longest having ~90 turns (So this sticks out in comparison to the other layers. It's just easier than tapping onto the middle of a winding)
Minimum current that all winding will be covered by the field:
1 mA (I know, it's very small...)
AWG of wire:
22
So, how do I determine the right dimension of the magnetic core? For now it's 40mm long and 5mm in diameter, which I know, is too long to properly concentrate the magnetic field, but it's for other considerations for now.
This is a real question.
