Passing mercury through a copper tube

[-NaN-]

How does passing mercury, salt water, etc thought a copper tube create electricity? and dose it create a magnetic field?

Welcome to PF;
... pretty much same way a battery works.

is this true of mercury or just salt water and how magnitudinous is the magnetic field at flow rate X? (Im not sure what increment would make a noticeable change in output?)

 

[Simon Bridge]

Why not try it and see?

Im hoping there's a more cost effective approach.

Let's see; the mercury or salt water is a conductor but not moving in a magnetic field, but so is the copper tube. I see no source of electrical current to cause a magnetic field.

... of doing what?
