Question

A) Increased

B) Decreased

C) Stays the Same

D) Becomes 0

An airplane is initially flying horizontally (not gaining or losing altitude), and heading exactly North. Suppose that the earth's magnetic field at this point is also exactly horizontal, and points from South to North. The airplane now starts a different motion. It maintains the same speed, and still flys horizontally, but is now heading SouthEast. The magnitude of the electric potential difference between the wingtips has... [Remember that the airplane is made of metal, and is a conductor] A) Increased B) Decreased C) Stays the Same D) Becomes 0

Explanation / Answer

The velocity vector becomes perpendicular to the magnetic field vector and hence the induced emf will be maximum. In otherwords, the induced emf increases as compared to previous
