The flexible loop in the figure below has a radius of 10.0 cm and is in a magnetic field of magnitude 0.160 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.210 s to close the loop, what is the magnitude of the average induced emf in it during this time interval?
