Coil32

Coil32 is inductance coil calculator, that allows to calculate single-layer and multi-layer air core inductors, ferrite core inductors and chokes, flat coils on PCB etc.Single-layer air core coils are calculated by R.Weaver's numerical method for helical winding.Calculation of multi-layer air core coils are based on Maxwell's formula for mutual inductance between two coaxial conducting filaments. Because of more exact complex numerical method some calculations may be long (few minutes).The app allows to calculate needed Number of turns for desired value of inductance, not versa. I hope this app could be useful for HAMs, Audiophiles and other radio enthusiasts who needs to make DIY inductors.I need for help from native speakers to translate this app in Indonesian, Portuguese etc. If you can give me the help, please email me.

They (sceptics) say Telsa Coil's ability to gain amplitude is IMPOSSIBLE, hahaha, they are right! BECAUSE they are using the wrong schematics! With the right schematics and invaluable coil calculator (like Coil32); self-gain resonant system is achievable! Have it a try!

it's a really good app. and you don't need to pay for it. it also really helps calculate metal detector coils.

The best real coil calculator. I have measured the coils designed with this program and the error is very small. This app is a must

It is great for ham radio use as most all builds neglect to tell one what to do if their wire gauge or form size differ from that stipulated in the build's directions.

Definitely a great app, recently made a short ground plane antenna for 40m using this app...it worked on a first attempt

Very easy to use.. Love it.. Simple and what I am looking for..

very helpful for coil design. It could b better if the wire condcutor specification could be defined by the user.

Excellent and wonderful tool that does complex calculations well. Tested!

Bri. G. Jun 22, 2017

It's a great app I love it and use it everyday

Sri. May 15, 2017

Use full application...

How about square core ??

When calculating a single layer coil, winding length is displayed in the wrong units. I set my inputs to be in inches but the calculated result for winding length says 30.62 inches. Should be either 30.62mm or 1.20 inches.
