Astudent takes a strand of copper wire and forms it into a circular loop of circumference of the student then places the loop in a uniform, constant magnetic field of magnitude that is oriented perpendicular to the face of the loop. pulling on the ends of the wire, they reduce the circumference of the loop to in a time interval of assuming that the loop remains circular as it shrinks, what is the magnitude of the average emf induced around the loop during this time interval?
