1. A plasma flow simulator, the simulator comprising a plasma vessel containing a plasma and having an at least partially rounded interior surface, an upper portion and a lower portion; conducting loops disposed around at least a portion of the plasma vessel, the conducting loops including a first conducting loop substantially orthogonal to a second conducting loop, and wherein the conducting loops are configured to yield magnetic fields that magnetically induce a first toroidal plasma flow in the upper portion of the plasma vessel, and a second toroidal plasma flow in the lower portion of the plasma vessel; and wherein at least one of the first and second conducting loops is disposed around an entire circumference of the plasma vessel.
