In a demonstration, a 4.00 cm2 square coil with 10 000 turns enters a larger square region with a uniform 1.50 T magnetic field at a speed of 100 m/s. The plane of the coil is perpendicular to the field lines. If the breakdown voltage of air is 4 000 V/cm on that day, the largest gap you can have between the two wires connected to the ends of the coil and still get a spark is
 a. 7.5  10-3 cm.
  b. 0.015 cm.
  c. 7.5 cm.
  d. 13 cm.
  e. 15 cm.

Question 2

A small airplane with a wing span of 12 m flies horizontally and due north at a speed of 60 m/s in a region where the magnetic field of the earth is 60 mT directed 60 below the horizontal. What is the magnitude of the induced emf between the ends of the wing?
 a. 50 mV
  b. 31 mV
  c. 37 mV
  d. 44 mV
  e. 22 mV
