Coil Building


Introduction: Coil Building

Coils are used for all sorts of things, like radio's, FM Transmitters, and even generators like the Tesla Coil.

What i'm going to do is show you how to make a coil fast and easy under a minute!

Step 1: Gather Your Supplies

What you will need is:

#18 Solid Core Copper Wire

Anything to wrap your wire around (preferably a 1/4" bolt).

Scissors & Wire Strippers

That's All!

Step 2: Cut About 10" of Wire

Measure 10 inches of wire, and cut it.

Step 3: Strip the Wire

Get your wire strippers and remove all insulation.

Step 4: Wrap the Wire Around Your Object of Choice

I used a 1/4" bolt but pretty much any round object will work.

Step 5: Now, Trim the Ends and Slide or Screw It Off

You're done!!!

    Using a bolt is very clever way to get nice coils... thanks for sharing

    it's a bit more detailed than that. a precision inductance meter is pretty much a requirement... as well as some core material.

    Thanks beacker just these coils are a pain soldering in checking if it's spot on its best just comparing on multimeters to save a lot of time and hassle to adjust the coils .

    Baeker your the first to mention that I have a precision gold here .how would I do that ?

    If you are building your own coils, you would need a meter. I have a cheap meter I use to guage inductance, but it fluctuates. There are guides on the internet if you search you'll be sure to find one

    What about the coil insulation not to short on itself?

    This coil will not short itself or anything around it if you use proper electrical power.
