I am making an inductor
- Air core
- Wire: 18 AWG guage
- Turns: (I am not sure ) but could be about 6000 turns
- The weight of the wire : 400 gram
- The coil wrapped by machine
- Coil is 5 cm
- Diameter of core is 1.5 cm
I used an inductance meter to measure the inductance and I got a weird reading of this large inductor = 3.7mH.
The DC resistance also is wire = 3.5 ohm.
Could these measurements be correct although it is a large inductor?
If so, how can I increase the inductance to 150mH?
Thanks guys for useful answers and comments
I just found i was wrong,
it is 5 cm lenght coil which is 50mm
the wire gauge is 18 AWG = 1mm
Flange of the coil is 1.5 cm = 15 mm ( maximum number of layers)
So one layer should be 50 turns (if roughly turned with no spacing)
So according to these numbers the turns should be 50 turn per layer * number of layer 15
50 *15 = 750 turns
So this inductor is about 650 to 750 turns not 6000 turns as i thought 😔
