Tesla Forums

Does anyone recognize this article (or possibly book chapter) simply titled "Tesla Coil."   I picked up an old photocopy a while back but can't seem to find the source.   It might be from a collection of old magazine articles, or possibly a book for science teachers.   Probably from the 1940's or 1950's given the style.     It starts on page 23, and runs (I believe) to page 30.   Attached is a scan of the first page.

The first paragraph is:

You can make spectacular demonstrations with this Tesla coil (Fig. 1) while you're studying the effects of high frequency current.  That's just what Nicola Tesla did with his famous induction coil back in 1892.  Although you will be experimenting with 60,000 volts, it is quite harmless because of its high frequency of 500,000 cycles per second.   Currents of high frequencies travel over conductor surfaces only, so that contact with it results in the current going over your skin to a ground, thus avoiding possible injury to internal organs. 

Thanks.

Hi,

I recognize the article... Back in the early 80s when I first started researching Tesla I found it in a book of electrical experiments at my local library. I believe it's actually from the 60s. I may still have the photocopies I made of the article somewhere. I begged my parents to buys the parts for me to build it and they reluctantly agreed but then I was disappointed to find that, according to our local electronics shop, the transmitting tube called for in the circuit was no longer being produced.

Later I ran across some pieces of a coil from a science fair and was able to build my first disruptive coil with them.

I'm working through Tesla-related magazine and newspaper articles right now in the new Tesla Articles section (http://www.teslauniverse.com/nikola-tesla-articles) but later there will be a plans database added to the builders section. If you have the rest of the article and would like to send it to me, I'll be happy to post it in case someone else might be looking for it.

Thanks,
Cameron

It's from a book called "The Science Experimenter" volume 1 published by Science and Mechanics Publishing Co. in 1958. I have a copy of the book.

Thanks!   I just ordered a copy.   

Looks very similar to 833C  Tube-type  coil mentioned in TCBA "News",  Vol. 10, #1, page 8.

I can't send a scan or I would.
