In a region of space where the magnetic field of the earth has a magnitude of 80 mT and is directed 30 below the horizontal, a 50-cm length of wire oriented horizontally along an east-west direction is moved horizontally to the south with a speed of 20 m/s. What is the magnitude of the induced potential difference between the ends of this wire?
 a. 0.45 mV
  b. 0.35 mV
  c. 0.30 mV
  d. 0.40 mV
  e. 0.69 mV

Question 2

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
