Rumkorff induction coils
Hi
We recently bought 2 of these things from Serrata. The instructions really only tell what the induction coil is but nor how to use it. We've just spent an hour or more trying to get the spectrum tubes to glow or trying to produce a spark and nthing is happening. It is actually making a noise so something must be happening we're just not getting the results we need. Has anyone got any suggestion or advice on how to use these things.
Thanks Krysia

Krysia,
Ev is spot on with that web site. It tells you all you need to know.
However....I bought a cool little device from Scientrific, made by IEC (I think) that you simply clip spectrum tubes into, and switch on. It's a no-brainer, and so much easier than induction coils.

Re: Rumkorff induction coils
Do tell, Smiley!! More info?? What is it called exactly! Sounds ideal!!
Re: Rumkorff induction coils
I have come across them a couple of times at the Physics workshops at the conference in St Mary's. They look great and seem to work really well, but we never have enough money to replace things like that, so we use the old ones with the induction coil.

Re: Rumkorff induction coils
The unit is called a "Spectrum Discharge Tube Power Supply", and yes they are a little expensive, but also safe, and easy to use. My only comment is that they need to change to glowing red on/off switch to something that doesn't glow, since the colour adds to the spectrum being emitted. We get around this by covering it with black cardboard. Supplier is indeed Scientrific.
Cheers, K

Re: Rumkorff induction coils
Thanks for all the replies guys. I knew I could rely on you. I had found that website Ev but the coils still don't work. Rang Serrata and they think they maybe faulty. I'm sending them back and trying Scientrific. Thanks again krysia
Re: Rumkorff induction coils
I don't know if your school is rural or not but the other alternative is to use an electrive fence supply

Re: Rumkorff induction coils
Hi Smiley , do you use the same power supply for the Crooke's tube. ( maltese cross and paddle wheel ones). Thanks

Re: Rumkorff induction coils
Well, haven't been asked to use those in the lo-o-o-ongest time, so no, I don't. However, maybe one could ask the question of the Scientrific mob, if it is even possible to do so?
Cheers, K
Re: Rumkorff induction coils
We have the power source for the spectrum tubes. It is made to take the gas tubes ie oxygen, nitrogen, helium etc. We use the induction coil for the crookes tubes and the vacuum scale tube sets. I don't know that it could be adapted to power the crookes and vacuum tubes.
