Spiral Coil Inductance Calculator

Action
Coil Mean Radius(r) 
Wire Coil Number of Turns(N) 
Coil Depth(d) 
Description (-)
The ratio of the magnetic flux to the current is called the inductance. Here we can calculate Inductance for Flat Spiral Air Core Coil.

Formula:
L=r2N2/(2r+2.8d)*105

where,
L = Inductance,
r = Coil Mean Radius,
N = Wire Coil Number of Turns,
d = Coil Depth.
