View Full Version : How do you make a coil arch?

If there were a coil next to a rotating magnet it would produce electricity, the coil like all coils used in generators has the two ends of the wire to make a circuit one end is nearest the core and the other is one on the outer of the coil.

How would I wire up this coil if I wanted it to arch from the coil to a contact instead of connecting other wires to the coil wires ?

And what would be the differences if when making the coil instead of using enamelled copper wires I were to wind the wire whist setting it in porcelain, would it make the coil into a superconductor?

I don't understand your terminology of "coil arch" = please clarify.

As for the coating of the wire used for a coil - no, it would not turn the wire into a superconductor. Superconductivity occurs only in wires of very special formulation at temperatures that are extremely cold.

Hello Ebaines,
Thanks for your help, in answer to your comment to clarify, The coil I am ref to is as a standard coil one would wind for use in electrical production by placing the coil beside a rotating magnet at 1400rpm, and by arch I mean the action of electricity jumping a void from its source to an earth or work (i.e like a electrical arch welder.) eerr thinking of an arch welder I may have answered my own question, one end of the coil wire still needs to be connected to an earth and the other can be used to form the arch, but which way round do I wire it up i.e do I use the one end of the coil wire that is closest to the core of the coil or do I use the end of the coil wire that is on the outer of the coil? And do I need a capacitor or super conductor or both or neither ? Does the ache jump from capacitor to capacitor ?

So the two ends of wire one has on a coil could I maybe connect on to the core of the coil and use the other end of the coil wire in conjunction with maybe a capacitor or superconductor to make the electricity stored on the coil (when beside a rotating magnet) jump from the coil across a void to a contact for earth or work.

*In addition thanks for saying about if the wire would become a super conductor by setting it in porcelain but can I ask why does it work for spark plugs that I believed to be a copper rod set in porcelain ?

Sorry to have go on a little, please just answer what you wish, I appreciate the help and information.

Doesn't matter - you're design will generate an AC current, so it doesn't matter which end is which.



And do I need a capacitor or super conductor or both or neither ? Does the ache jump from capacitor to capacitor ?

A capacitor can be used to store energy and ultimately deliver a bigger surge of power, in a discontinuous fashion. I don't understand why you keep asking about a superconductor - what does that have to do with welding? A superconductor can carry more current with negligible loss, but woiuld add huge expense - are you thinking about some sort of super welder that produces more power and needs to carry more current than traditional welders?




In addition thanks for saying about if the wire would become a super conductor by setting it in porcelain but can I ask why does it work for spark plugs that I believed to be a copper rod set in porcelain ?

No - there are no spark plugs using superconducting materials that I am aware of. A spark plug made with a superconductor would cost multiple millions of dollars! The function of the porcelain is to provide a heat-resistant insulator.

No I was not thinking of a welder, I was just in confusion as I thought a spark plug acted as a super conductor because the I thought that porcelain set around a copper rod compressed the electrons because they have less space on them surface of the copper rod causing the to be forced through quicker ?
