A Conducting Rod (Length = 2

Multiple Choice

A conducting rod (length = 2.0 m) spins at a constant rate of 2.0 revolutions per second about an axis that is perpendicular to the rod and through its center. A uniform magnetic field (magnitude = 8.0 mT) is directed perpendicularly to the plane of rotation. What is the magnitude of the potential difference between the center of the rod and either of its ends?

A) 16 mV
B) 50 mV
C) 8.0 mV
D) 0.10 mV
E) 100 mV
