Re: [TCML] Magnetic Quenching
Perhaps you could bundle up pieces of bailing wire to create a core.

Good question!
I think this area is also perfect for further research. If you think about
the Poulsen & Duddell Singing Arcs & transmitters, they were in many ways
Tesla circuits, or at least similar variations. Granted, different
application, but some of these transmitters were pushing over 250kW, with
low voltage high current arcs no less! They were also using large (but
crude by today's standards) electromagnets...much like those in the Tesla
lectures. I think this concept could really prove fruitful for TCs, which
would seem simple in comparisson... I know of some experimenters in Croatia
that had some success with this, using even simple tungsten gaps with NIB
magnets.
I think it is too heavy to ship to anyone to play with, but I have a 2 foot
tall water-cooled electromagnet with room for a 7" round core (that
unfortunately is missing from it!). It would be a great monster to
incorporate into this technology somehow. I got it to try and figure out
the singing arcs one day in the far future. But time and cost, the core is
a vital part obviously, and getting even a chunk of steel that size is an
ordeal - much less proper laminations to make a "real" core. It was made
by Varian, and has 6 or 7 coils potted in (?)Epoxy, probably ran from 480V,
and even without the core weighs a few hundred pounds.
If anyone has any ideas of what to do with it (or what it might actually be
from), I often thought of just filling it with scrap steel and machining
some field portions for the top and bottom. I wish I could "slice" the
individual coils out of it to have smaller (& lighter!) versions to play
with, but the housing around them is massive, and it seems to well-built to
hack into/apart. It is probably around 16" in diameter. Maybe a start
would be to find some 6" sch 40 [scrap] steel pipe for the core...? Not
sure even where to find that...? Might be a hernia in the making...

However, there are few quantified, before-after tests, and the area is
ripe for further research. The technique should be effective for both
static and rotary gaps.
