Helpful coil calculators. 



These tools can be useful for finding various properties and dimensions of coils. 





Coil resonant frequency
calculator 




This calculates a coil's resonant frequency (f), inductance (L), and self capacitance (C), given its length and diameter as input. 














This calculates the possible dimensions: lengths, diameters, etc.,
given the desired self resonant frequency (f_{r}) of the coil as input.
Assuming that the coil will be a quarter wave oscillator ( λ = 4 ℓ_{w}). 














This calculates the possible dimensions: lengths, diameters, etc.,
given the desired self resonant frequency (f_{r}) of the coil as input.
Assuming that the coil will be a half wave oscillator ( λ = 2 ℓ_{w}). 





Wire length spool calculator 




This can be useful in obtaining the length of a wire on a spool.
Entering the weight of the wire on the spool in ounces, and the wire's gauge, this will calculate the length of the wire on the spool. 









Capacitance
calculator 




Calculates the necessary capacitance (C) for a tank circuit at a given resonant frequency (f), and inductance (L). 









Primary coil turns
calculator 




Calculates the possible number of turns of wire for a primary coil, with the given input of the coils mass, diameter of the coil, and the wire's gauge.
