A metal blade spins at a constant rate of 5.0 revolutions per second about a pivot through one end of the blade. This rotation occurs in a region where the component of the earth's magnetic field perpendicular to the blade is 30 mT. If the blade is 60 cm in length, what is the magnitude of the potential difference between its ends?
 a. 0.24 mV
  b. 0.20 mV
  c. 0.17 mV
  d. 0.27 mV
  e. 0.34 mV

Question 2

A conducting rod (length = 80 cm) rotates at a constant angular rate of 15 revolutions per second about a pivot at one end. A uniform field (B = 60 mT) is directed perpendicularly to the plane of rotation. What is the magnitude of the emf induced between the ends of the rod?
 a. 2.7 V
  b. 2.1 V
  c. 2.4 V
  d. 1.8 V
  e. 3.3 V
