Hey, I've been wondering about the behavior of flowing charged particles lately. In particular, imagine that I have a tank of charged fluid. Lets assume this charge density is 1 C/cm^3. I then allow the fluid to flow through a pipe of 1 cm^2 cross-sectional area at a rate of 1 m/s. Thus there is a charge of 100 C flowing past a fixed point on the pipe per second. My question is, would this flow produce a magnetic field equivalent to a 100A current in a solid conductor? I've read up on magnetohydrodynamics but it doesn't seem to answer this question on any of the sources I've found.
