An airplane is flying horizontal and heading south in a region where the earth's magnetic field is directd vertically. The planes wings and body are made of a continuous conducting metal. For these conditions, the tip of the east-side wing would be at a lower potential than the west-side wing. I just want to check if my reasoning is correct. OK, so this is true because since the magnetic field is pointing perpendicular to the plane, the charges would migrate to one side?
