The figure below displays a circular loop of metal wire in a uniform magnetic field pointing into the page. The radius of the loop is 13.0 am and the magnitude of the field is 0.160 T. You grab points A and B and pull them in opposite directions, stretching the loop until its area is nearly zero, taking a time of 0.180 s to do so. What is the magnitude of the average induced emf in the loop (in mV) during this time? x x * ↑
