A DC induction arc,might be probably similar to welder DC arc that may show some similarities. But it would seem the best example for a dc induction arc is to use a huge air core inductance in DC. When we break the DC circuit, an arc will always form at the breaking points. For a 1000 ohm 60 henry coil @ 400 volts, it is easy to procur a 1/2 inch long arc, and I think these arcs are harder to estiguish then their AC counterparts. A lot is unknown in this category. A man named Joseph Newman built a copper magnetic motor, where he claimed that these DC induction arcs occuring at the DC commutator, were in fact acting as back rf emf spikes on the battery supply, so that the battery was getting charged back up while powering the motor. I myself built an entirely different version of a copper magnetic motor using 4 of these 80 lb 60 henry coils, and was able to rotate a 50 lb magnetic rotor some 300 rpm with the air core coil system. It was here where the impossibility of extinguishing the DC induction arc became apparent as a real problem. The amount of voltage that appears between the separating electrodes of the commutator are also dependent on the speed of separation, and a longer arc is always procurred at a faster separation rate. The normal practice is to provide an alternative pathway for the induction arc, such as a florescent bulb, which is what Newman did, by putting bulbs in parallel to the arc. These then function as voltage dependent parallel pathways that only open as a parallel circuit across the arc, when the extra voltage created by the induction arc begins to act. The key here is the word "extra" voltage. When the magnetic field of the inductor having a DC magnetic field is interupted, the magnetic field lines collapse back through the windings, which is what generates this extra voltage. I am unfamiliar with aspects of DC welding, and ferromagnetic counterparts of the DC induction arc. But what sems evident is that it is the SPEED of the magnetic collapse that creates this extra voltage. But this is not at all a one time event, or a delicate balancing act between magnetic collapse and arc formation. The process is very self sustaining, and the air core DC induction arc is very hard to extinguish, and will easily go on in duration until the electrodes may start some heating problems. Thus we can create a DC induction arc that can function for long durations of time. The differences between a ferromagnetic DC induction arc effect,and the air core may be due to the following; the air core induction coil has a magnetic field that distributes itself widely into space around the coil, so when collapse of the field lines occurs, they must generally travel a larger distance of space when that collapse occurs: BUT, the ferromagnetic inductance has its magnetic field confined to the volume of the ferromagnetic core, so the speed of its magnetic field collapse may be lesser in that lesser volume of space. Now that I have gone somewhat off topic: lets get to the rest of the story...
I found out that a copper magnetic motor could be made in miniature using NIB magnets and radio shack coils. There was a problem of construction. Here a similar topic is evident, how can you make a holding assembly for coins in a V position. My simple first try solution: Go to wallmart and buy a Tinkertoy set! Its expensive, but sometimes you have to throw money at a problem. Perhaps the old erector sets with metal parts could also come in handy for constructing an electrode assembly. My particular solution for the DC water arcing scenario is to first build a tinkertoy holding assembly to position the coins in a V gap formation. I will try something different since immersing the coins into a water may be problematic for making underwater arcing, where in past effects surface arcs instead take place. Instead I will position the V coin gap over a funnel. I have a 5 gallon Wall mart Cooler that can establish a gravity flow through plastic tubing of continous water past the V coin assembly. This is going to take a while to construct. This limits runs to the time of draining. My first trial run will use silver electrodes. This probably will be an unfit substance, a throw away batch for the garden. I am worried about high silver oxide formations at these higher voltages. Maybe then I can graduate to using one gold coin electrode. Any consensus of which polarity to use for the gold? I would suppose the one that would be considered more Negative? For those wishing to experiment with air core DC induction arcs, let me recommend a least expensive alternative. Years ago in the factory, we used spools of paper coated steel wire, the same kind of wire found on bread bags for sealing; to use for twist tying boxes of plastic prduct contained in plastic bags. A spool of this steel wire has a fairly high resistance and can make a decent induction arc. Perhaps these can be found on EBAY,so let me know if anyone finds these, as I may wish to purchase these myself. An important aspect of creating the DC induction arc is chosing a "resonant" value for the filter capacity used to smooth out the DC ripple, that all built power supplies use. The DC induction arc becomes somewhat laser-like in its actions when a resonant capacity is used. I have worked out a scope experiment to determine if this resonant value is correct, where I think it should be 1/4 of the value that the inductor uses for 60 hz resonance. This is because 60 hz becomes 120 pulses per second when converted to DC.
