A metal blade (length = 80 cm) spins at a constant rate of 10 radians/s about a pivot at one end. A uniform magnetic field of 2.0 mT is directed at an angle of 30 with the plane of the rotation. What is the magnitude of the potential difference between the two ends of the blade?
 a. 5.5 mV
  b. 6.4 mV
  c. 3.2 mV
  d. 11 mV
  e. 13 mV

Question 2

A 20-cm length of wire is held along an east-west direction and moved horizontally to the north with a speed of 3.0 m/s in a region where the magnetic field of the earth is 60 mT directed 30 below the horizontal. What is the magnitude of the potential difference between the ends of the wire?
 a. 36 mV
  b. 18 mV
  c. 31 mV
  d. 24 mV
  e. 21 mV
