Well a lot of this is flexible - the cell is relatively small, a glass cylinder (length ~100mm, circular face diameter ~70mm). It would be filled with air of varying pressure and need to heat it to ~200 degrees max, I am unsure of how to do the calculation to figure out the Watts required...

Okay I have done a little more research on this - so now I understand that without insulation it won't work at all because they will short-circuit. BUT using a twisted pair is pretty easy because you can just coil them with a drill and then they will stay together like that - this minimises...

Ah oh dear, really :( I just thought that it would nicely break down into summing magnetic field components from 8 straight finite wires, which ultimately makes the problem finding the field at any point (x,y,z) due to a finite wire [I'm already not very comfortable with this though, since I've...

That's the problem though, like I said I'm not very familiar with resistance wires but intuitively I think if the goal is for heating then I'd assume they wouldn't be insulated - so I'm not sure how twisting would work without insulation from a safety point of view if the high levels of contact...

I'm looking for heating wire (to ~200-300 degrees Celsius) that won't disturb a ~weakish applied magnetic field significantly - I would be wrapped it helically around a glass cell which is placed inside magnetic field coils. So if I had two parallel sets of non-magnetic wire attached and coiled...

Homework Statement Not exactly a homework problem, but the actual working resembles it. Basically it is a standard calculation for the magnetic field between a set of Helmholtz coils, except with a rectangular loop instead of circular ie: two identical rectangular magnetic loops (dimensions...
