The Nile River runs from east to west. Assume the water in theNile is electrically neutral while still conducting, and that theions (both positive and negative in equal concentration) arecarried with the flow of the water. What would the electricpotential of the north side of the river be in comparision to thesouthern side due to the lorentz force on the ions. Remember thatthe magnetic field of the earth has northern and southerncomponents.
