I knew somebody would go there.  It doesn't matter if it oxidizes, it's
still got its speed, even if it's a vapor, and it's going to get to that
bottom gate.  Then it goes around again.

Even without it being a lodestone, any moving metal produces a field. 
Bleeding off the energy of that field is one way to slow the vapor, and
keep it all from going critical.

You could also put a new gate at mid-point, and vent the plasma
wherever.  But if it's got up to anything measured in c, brace yourself
for the shift in gravity.  :)
