SUMMARY

Passing mercury or salt water through a copper tube can generate electricity similarly to how a battery operates. The discussion highlights that while both mercury and salt water are conductors, they require movement within a magnetic field to induce an electrical current. The magnitude of the resulting magnetic field is contingent upon the flow rate of the liquid, although specific increments for noticeable changes in output remain unclear. The conversation suggests exploring cost-effective methods to harness this phenomenon.

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?)
 
Why not try it and see?
 
Im hoping there's a more cost effective approach.
