Transcribed Image Text:**Problem Statement:**
The flexible loop in the figure below has a radius of 12 cm and is in a magnetic field of strength 0.17 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.25 s to close the loop, what is the magnitude of the average induced emf (in mV) in it during this time?
|E| = ________ mV
**Diagram Explanation:**
The diagram shows a circular loop situated in a uniform magnetic field. Green crosses represent the direction of the magnetic field, pointing into the plane of the loop. The loop is labeled at two points, A and B, which are the points where the loop is grasped to be closed. The arrows indicate the direction of manipulation.
