I read the following problem on a text book:
A airplane flies at a constant speed of 680m/s perpendiculary to earth's magnetic field (of 5x10^5 T). The wingspan of the airplane is 9.8m. What is the induced voltage?
The answer the book gives is: E = BLv = 0.4066V
But I've been wondering if this is true. There isn't and enclosed loop. How can a simple wire moving on a magnetic field induce voltage on its terminals?
