# Magnetic field and airplane scenario.

## Main Question or Discussion Point

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?

Correct, and this actually does happen on airplanes. Ballpark calculations I did say there's about .1V potential difference on a typical airplane!

Sweet thanks!
Another quick question, does the side of the plane that tips toward the earth matter?(e.g the west side vs. the east side?).

I'm not sure what you mean and why all of a sudden the plane is tipping towards the Earth.

Wow. Sorry I confused myself by looking at the wrong problem.
I meant to say that in the question it says that the east side would be at a lower potential. Why is the east side the side that experiences lower potential and not the west side?
