Answer

A voltage difference is induced between the wingtips of a moving airplane. A momentary current flows, but then stops, because the charges don't have a complete circuit to flow continuously.

Work Step by Step

Another way to approach the problem is to see that electric charge builds up on the wingtips until there is a voltage difference that counteracts the original, induced voltage difference.
