Eric, This is a direct consequence of the formula for computing the magnetic vector potential. When all particles flow in a narrow channel, in the same direction, all of their (vector) contributions to the potential are nearly parallel and are additive.
When they move in random directions, the vector potential is a sum of random vectors, so destructive interference greatly attenuates it. Toy examples of a four particle fusor vs. an arc might look like - | | <==== V <==== ---> <--- ^ | | The fusor will only produce relatively small magnetic vector fields. Yes, I think your diagram does convey a correct concept for a plasma arc impacting an +ion rich surface. The impacting electrons will acquire extra energy from the momentum store in the magnetic field. -- LP Eric Walker wrote: > On Sat, Feb 15, 2014 at 11:53 AM, <pagnu...@htdconnect.com> wrote: > > This effect is not very significant in chaotic plasmas, such as in a >> Farnworth fusor device since there is too much field cancellation due to >> random motion.
