The electron drift velocity in a wire is about 0.1 mm/s.

If a coil were constructed from a helical nonconducting tube and filled with mercury such that if a current was passed through the mercury, a magnetic field would be detected. If then the mercury were caused to flow through the tube, would there be a measurable change in the magnetic field?
