Yeah but which one? ..cause i checked of dozens of that ?Well then you would need a formula for the inductance of a coil of given length, diameter, number of turns and magnetic permeability.
What value did you get for the inductance? That should be pretty easy.Yeah but which one? ..cause i checked of dozens of that ?
i got one answer which give me 3 turns which is ridiculous !!!!
also where do i find magnetic permeability.?
Using the permeability of air (not relative) in the equation, I got a few turns, but it was considerably more than 3.I believe as used in most formulas, permiabiality is relative, where standard is a vacuum =1, air not far away.
Why does seem 3 turns seem out of line, remember that you are at the top end of the FM radio range.
The equation I used gave me 7.4368 turns.Using Allied's Coil Winding Data , L = about 2/10 μH, giving around 8 turns, give or take.
i know u can use f = 1/sqrt(LC) for find L then which equation you use.The equation I used gave me 7.4368 turns.
No, f=1/(2*pi*√(LC)).i know u can use f = 1/sqrt(LC) for find L then which equation you use.
