Question

 A flexible circular loop 8.00 cm in diameter lies in a magnetic field with magnitude 2 T, directed into the plane of the page in the figure. The loop is pulled at the points indicated by the arrows, forming a loop of zero area in 0.300 s.

  1. Find the average induced emf in the circuit. 
  2. What is the direction of the induced magnetic field 
  3. What is the direction of the induced current in R? (From a to b or b to a) 
  4. If you rotate the circular loop as the top part out of page, what is the direction of the induced current in R? (From a to b or b to a)
  5. If you move the circular loop inside the magnetic field with a constant velocity toward the right, what is the direction of the induced current in R? (From a to b or b to a)
