What is a room temperature liquid that has an electric conductivity

shameless self bump

Mercury isn't AS conductive as copper, but it's pretty close

I guess so, do you think it would interfere with a magnetic field going around a copper tube its inside of?

>>8681099
So what are you trying to do?

railgun

the rails in most guns require extremely tight bullets to decrease the amount of arcs on the rails whoch would have burned up the rails after muliple uses

I figured I could use hollowed out copper tubes or rectangluar rods as rails filled with a conductive liquid. so that a sabot-like shell casing that would stick into the liquid via long slots along the rails and hold the projectile until it was time to exit the barrel

>>8681372
so essentially a frictionless railgun

You're going to splash mercury everywhere.

thanks for the input

So one, you need two rails. Second magnetohydrodynamic instabilities. In liquid metal pumps, essentially railguns for liquid metal, above a certain current the flow becomes unstable due to magnetohydrodynamic effects.

What would prevent the current from flowing from one rod to the other via the mercury itself?
