Sorry, I am not a physics major - I apologize in advance if this question is ignorant or if this was asked already. What would be the most effective as a Magnetohydrodynamics weapon? Assuming normal ionized air, would a liquid (liquid silver and salt water) or some type of plasma (anything?) be better for distance traveled and / or electrical conductivity? Or is something else better than either of these? I was playing a science fiction video game where a MHD weapon was used and there was a debate among my group of friends as to what would be best. I just wanted to know what really would be the best for this. Thank You!!!
